R/T - sticker says 16 (16.9) I'm taking it on the raod for the first time over the Thanksgiving holiday... I pray that there's sunshine the entire trip:Racing:. I'll post my HWY MGP when I get back.

In the city I am getting 17 mpg hwy 30 - 31 mpg.

In the city I am getting 17 mpg hwy 30 - 31 mpg.

Brokay why not post an introduction post in the newbie section and tell us about yourself. That is pretty good mpg on the highway.

I have now racked up around 900 miles on mine I got 22.9 MPG on my first tank. It was 3/4 full when I bought it and i didn't fill up until i ran that out so I've only been able to calculate MPG once so far.

Oh and mine is FWD.

*** UPDATE 11/16 ***
I filled up on my way home tonight and I got 24 MPG on the nose.

- Dan M

I have a SXT Avenger with the 2.7L V6, I do a combination of driving in city and highway. I average around 26.5 mpg, if I get on the highway between 28-29 mpg.

I have a RT and drive approximently 300+ miles per week. My mileage started off a little low at 18 but has since picked up. The last tank I got 20.5 mpg, and thats mixed driving, lots of stop and go because of rush hour in the morning and at night. I rarely get to mash the pedal because of traffic as well.

I'm at 4000 miles now, and just recently added air to my tires. When warmed up, the evic reads about 34 psi. I know the door says 32 psi, but honestly, unless your pumping in 50 psi or something over whats rated on the sidewall you need not worry. I would estimate this tank with the higher pressure at 21 mpg, maybe more. I think thats pretty good for the type of driving I do.

Typically my fuel light comes on at about 275-285 miles into a tank, which I typically run up to 305-310 miles per tank before the refill. When I refill I constantly notice that I'll have 1.5-2 gallons left in the tank. I base this on 16.9 gallon tank, where I can only fill to 15 or 15.5 gallons. At 20 mpg, that would put me right about 330-340 miles per tank.

Since the air pressure increase, my fuel light didn't turn on until an amazing 300 miles in. I think I'm already near 310, and I could probably get to 350 or more easily, though I rather not run out, so I'll probably fuel up and calculate the mpg on my way home tonight.

If anyone wants to try, I would recommend at least 32 psi in all 4 tires when cold, and then after driving and warmed up, check either with a guage or the evic to verify 34 psi. I think mpg wise, you will be pleasantly suprised. I noticed no decrease in handling.

When I had my magnum, it was the same way only worse, I needed probably 34-36 psi to get decent mileage in that car and it still wasn't as good as the avenger, and I had the 3.5l engine in that too. The sticker there listed 32 psi, and that KILLED my gas mileage as well as making that car handle like junk. Heavier car, RWD plays a part but tire pressure really was key to that one imo.

Good Info, I actually had my tires at 34psi when it started getting cold here... I would notice that in the morning, while it's cold, the low psi meter would come on and it'll say one xx when I get in the car but by the end of the day it'll say a higher number. right now I'm currently at 34psi and have yet to monitor my mpg.

This is what precipitated my filling up the tires. The TPMS sensors were going off when it got cold, and when I looked they were actually running a little low to begin with...they went off at about 26-27 psi. They would warm up when I drove to about 30-31. So I filled them up to 32 with my handheld gauge and then checked after driving to work one day and the evic read 34 psi. Cold they seem to be right on about 31-32 psi.

I may even increase them again, but it varies with the weather. Of course nitrogen isn't supposed to vary as much, but its harder to find a place to fill them when you need to. So I haven't gone that route yet.

Well I filled up yesterday and much to my own suprise I was up to 21.57 mpg! :) So the air pressure can have a drastic affect on gas mileage.

I've stopped resetting the avg mpg on the evic because I think it becomes more accurate if you leave it alone. When I did reset it, it was always about 3 mpg off or more, now its only about 1 mpg off. I always check my mileage using math anyways. ;)

with my bone stock SE, I'm averaging about 32mpg with 99% highway miles. Of course I also drive like a granny and never take it over 80mph. :old:

All good info. What not only a great site, but a great forum.

I have a RT FWD and I'm not certain what I get so I'll definitely give it a shot. I typically drive 30 miles a day and I have already racked up 4000 miles. (Thank god for my lifetime warranty)

I did notice that I am not getting the best mileage in the world. The air pressure gage came on and I took it to a tire place which said all tires were 10lbs low. After that I have noticed my fill-ups last longer.

Another thing that hurts my mileage is that I am a resident of southern California and I really believe that I need to get my air filter replaced because of smoke from the wildfires. I'll post another update soon to show my mileage and then again when I get my air filter replaced.

Ya, 10lbs low would really make a difference. When mine were coming on they were only about 5 lbs or so (i think) and I really saw a difference.

I will be going to Greensboro, NC this weekend and will be monitoring my mileage. When I get the chance I will post my findings. Looking forward to comparing it to the mileage I got with my last car. I was getting between 22 to 24 city and 32 to 33 hwy in my 2003 Neon.

Well I have gone 218 miles so far and I have just reached half a tank. when I go to refill tomorrow I will calculate my mileage.

Ok driving to Greensboro and back I got 25 MPG. About 1/3 of the way back I filled up and started reset my trip meter. This trip was my first tank of gas. My gas mileage should go up after a couple thousand miles.

on my 3rd fill up I got 23.6 MPG.

Has anyone thought about or actually installed a preformance chip to thier avenger? I saw that dynamic tuning has one for sale for 10 dollars and supposibly it increases hp by 40 and can increase your MPG by 10. This looks like a scam to me so I'm a bit weary of buying it. Has anyone heard of this?

http://cgi.ebay.com/ebaymotors/PERFORMANCE-CHIP-DODGE-AVENGER-2008_W0QQitemZ260184526248QQihZ016QQcategoryZ33597 QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Steve do not be fooled by their claims. Always go with a company thats been around for awhile and has spent alot of money on R&D. A $10 chip is just a $10 pos chip. Jet has a Stag1 and Stag2 performance chips for our Avengers. Even though they are not cheap, they do work as claimed. I had one in my Dakota 4.7L V8, it was a Stag2. It did make a big difference in HP and TQ. Because it was a Stag2, I had to go with an CAI and true duals. With a Stag1, all you should do is get an CAI system. I have the Stag2 and a custom made CAI and a Flowmaster 40 series muffler for my Avenger just waiting to be put on. I will be posting my findings soon on the setup I have. So, just wait and keep watching for my posts and pics in a month or two.

Remember the old adage "you get what you pay for"

Yes steve, those are bigtime scams. The jet chip is not however. To add to my gas mileage findings as well...the weather got a lot colder this past week, and my tires saw a drop of about 1-1.5 lbs. My gas mileage went down by about 1 mpg with this last tank..

After reading about the tire pressure I checked mine last week.. I put them at 34 psi.. I went away for the weekend... AS near as I can figure I got around 24 mpg out of my R/t AWD.. i have just over 1300 miles on it now.

I went to New Bern NC over the weekend and had over 100 miles to drive on a full tank when I got there and back home and I stayed between 65 - 80 and got up to 100+ a few times... I love this car.

KD Have you topped it out yet? If you have what is the top end? I have a SXT with the 2.7L and I have gotten about 123mph on a flat road with no wind. That's a stock 2.7L.

Wow nice! I haven't had a chance to test mine out...too scared of the ticket I guess. Maybe if I take it up north...then again I'd be too scared of the deer! LOL

Hey AvengerRT are you anywhere near rte 96
I lived in Brighton for a short while and 96 was pretty good for short runs.

I don't have any ways to clock the actual speed. a few weeks back here in the DC area, I was coming down from an onrap to the highway, but not onto a flat/straight road, I reached 115 and I'm not sure if that was max, I doubt it.

Here is a picture from some point in my trip I was at 110mph. Just think if I would've done the speed limit the entire way to NC, I would have had more than 100 miles to go on my tank.

38

The trick will be to video the speedometergoing up in speed while the gas gauge goes down in fuel.

dumb question here.. CAI???? cold air intake?.... i thought the set up on the avenger already allowed for that?

Funny, I've been running up and down 96 all day test driving kia's for some tpms testing. It has its spots but I saw a few cops out today.

Mostly my drive in is on 696. Not a great place for that..

dumb question here.. CAI???? cold air intake?.... i thought the set up on the avenger already allowed for that?

Cold air intakes like K&N give better air flow than stock. You do not gain much HP but you air to fuel ratio is better.

There used to be a nice two lane on the outskirts of brighton. On the east end I think. That is straight for a good distance and not to much traffic. And tree lined. But hey that was 20 yrs ago.

At night 70 near Kingston NC is a great road I'm talking about a couple of miles of all straight road. Of course at night you'll have to watch out for the animals (Drive smart and safe) but it's a straight road. I didn't take that road this time. I stopped in Wilson NC and the GPS had me going through Greensville, 43 south.

It probably has a strip mall, medical offices, and a mcdonalds on it by now lol :p

Ha, and two trees with all the deer in the middle of the highway.

Oh yeah, that too. I'm sure it can't be as bad as it is here in my area.

Depends on the day lol....

got a car deal once when a deer ran out in the road in front of the dealeership. tThe ford F-150 was totaled and so was the deer.

Did you buy the Deer or the truck?

The deer....it looked better

I know that section of road you're talking about. My wife grew up in that area and has family there. And there are a lot of deer in that area among other critters. My sister-in-law was driving down to her parents house from Raleigh and saw a baby bear along that stretch of highway.

I've been wanting to see one, not anywhere on the highway but far off somewhere on the road or something... but no such luck. I did about 125 on that road at night when I had my Jetta. I don't think I'm going to try it at night again... maybe just once more... we'll see

Hehe, once when I was up north with the contour and out late, i decided to try and top it out. I think I got to 110 before I got scared. But it was foggy and hilly, and thats pretty scary. Fog is bad enough, but nothing like cresting a hill in it doing 100 not knowing whats coming next.

I may need to just go to the track lol. I just think I would feel slow compared to all the suped up cars there...

I agree... LOL cars with 700hp flyin down the track...

Ok my 3rd tank is done. I stomped on the gassome this tank and still got good mileage as far as I can see. Anyway I got 23.15 MPG Averaging the three tankfulls I got 25 Mpg. I am happy with that. :smileup:

Nice! Sounds like you are doing well with it. What do you have your tire pressure at?

I did a lot more than normal of city driving in my R/T, I just filled up again and got 21.5 MPG. And I also had my foot into it more than I should have. Sometimes you just feel you have to.

EPA estimate is 16/26 so that's combined avg of 21, yep, that's what I got.

- Dan M

Nice! Sounds like you are doing well with it. What do you have your tire pressure at?
I have my tire pressure at 34pounds. One of these days I am gonna get a stopwatch and clock the 0-60. I have played with it and it is quick. It just makes me grin so much. It is an addiction.;)

Thanks for the info! :)

Averaging 28, best has been 30.9 (all highway), worst has been 25.4 and my wife is a lead foot. Loving the little 4 banger.

Air pressure? Just wondering, even though its the 4 banger. :)

We have the Premium package which gives you the numbers for each tire. I've yet to be able to get the same pressure in all four tires on the display. I filled them all to 32 (cold) measured by an air gauge last weekend. On the display they seem to be fluctuating between 31 - 33.... Jury is still out on this tire pressure monitoring system.

Hmmn, mine are pretty much always the same..might take one tire to catch up once in awhile but i guess my little digital guage I check it against is pretty consistant...

Has anyone tried putting nitrogen in thier tires? I used it in my tires in the last car I had. The pressure didn't flucuate with temp. changes and it remained the same +/- 2 pounds oveer a period of 8 months. I would use it now but having trouble finding somewhere to get it. The dealer that i got it from went belly up last year.

I want to do this, I just don't have the money to pay for it right now. Once in awhile the tire places around here will have a free offer but its been awhile since I've seen it. I also want them to put in 34 lbs, and not sure if they will do anything other than mfr recommended...

Well if you're placing the air in your tires yourself you could always go to a gas station and add 34psi. but nitrogen... never tried it, I wonder what the effects are

Well if you're placing the air in your tires yourself you could always go to a gas station and add 34psi. but nitrogen... never tried it, I wonder what the effects are
Well with nitrogen you don't have a pressure flucuation when the temp. changes, you don't get condensation, and nitrogen doesn't leak out like regular air. Not to mention that when youuse regular air from a compressor that some times thier is condensation in the compressor that gets transferred to your tire. I have actually seen where a mechanic removed over a cup of water out of a tire that he was changing. The rim had rusted and pitted.

Well if you're placing the air in your tires yourself you could always go to a gas station and add 34psi. but nitrogen... never tried it, I wonder what the effects are


Yes but I don't think there are manual nitrogen filling stations yet. Though air can be added, because iirc, its not "pure" nitrogen that ends up in there, unless its completely empty from the start...

Hmmn...we have big tanks of nitrogen at work...but I don't think its quite the same deal lol..

The dealership had some sort of machine that sucked the air out and then put the nitrogen in. And if you were tto get a flat you could use regular air to fill it back up then come back to the dealership and have it replaced with nitrogen for free:D. I don't know what anyone else might be doing. And haven't found anyone else that is doing the nitrogen filled tires around here.

Hmmn...well then thats maybe what they are doing. I've yet to have it done, but I know costco and belle tire around here will do it, but I think they charge you unless you bought the tires from them in the first place. From what I've read on the net, I just guessed they pulled the stem and let the air out, and refilled with nitrogen. I guess the best results are acheived when theres more nitrogen and less "air". I just thought there was always some sort of mix.

I think pep boys offers that. I know at least 1 local dodge dealer offers it as well.
I think if you call around to some tire places you may find some that offer this as well.

Ok after the first tank of 89 octane, in the cold weather, where my tires were about 31-33 psi (cold to warm) I ended up with 20.4 mpg. The weather is getting a bit warmer which should bring the psi up a tad and mean less idling to get warm time. I am expecting a slight increase in mileage on what will be my second tank of 89 octane.

At this point, i've noticed no difference in performance. Well I guess I would like to say it almost feels more sluggish, but I just don't believe that octane is going to have that effect on it. So I'm figuring thats just junk in my head.

if anyone's curious, i just checked & it sez 12.8 mpg - no typo.

but in the car's defense, along with the reasons already noted above, i warm it up a good ten minutes before going anywhere, pretty well always start off with the seat/coffee warmers on (definitely in the mornings), i'm a smoker so keep the sunroof at least 1/3 the way open all the time so the heater's going constantly, not to mention the stereo is always cranked (i really like having more watts than HP though :)

there's lots drawing off the car, so actually i'm not too surprised. i haven't plugged it in yet either, even when it hit -28C in the mornings for a bit and i haven't reset it since i bought it (9200 km ago). still happy with it tho.

oh ya, i use 89 if they have it, 87 if they don't. (i just cut/pasted this from a similar conversation goin on btw)

Well just got back from my latest trip to Greensboro, NC. ON the trip down I got 28.3 MPG. On the way back do to conditions and operator my mileage dropped to around 18 MPG.

I don't really trust the mileage calculator. It says I'm constantly getting worse gas mileage than I did with my V8 Dakota which I find hard to believe. I have yet to even push the car over 3k RPMs as I feel I'm breaking it in still with only 500mi on it.

I get like 260 or so miles to the tank if I recall. I'm only on my 2 full tank.. which I may fill up tonight or tomorrow for the 3rd tank.

As far as the Nitrogen goes..the gas mileage marketing aspect is a joke. Nitrogen leaks far less than regular air. Its good for tires that lose a few PSI over a short time. That's where the gas benefit comes from that you hear the hype. Don't bother with it unless they want to do it for free, your replace tires, etc. Don't pay to have this done.

Well lets see properly inflated tires help with better handling, safer driving (IE: better handling). less wear and tear on your tires, and yes 3% better gas mileage.
Most of the people I know don't regularly check thier tire pressure so the fact that nitrogen doesn't leakout of your tires like air makes a big difference to them.

If you're not smart or motivated enough to check your tire pressure monthly, I don't believe you should be allowed to drive.

I ride motorcycles and people like us constantly check our lights, tire pressure and wear on the bike. I do the same with my cars.. I check for leaks, I make sure the tire pressure is there, etc.

If you're that careless about taking care of your car, I highly doubt you'll be any more cautious in driving. I beleive in individuals taking responsibility for themselves. Ignorance is not an excuse.

I'm getting 16 mpg city and 25-26 mpg highway. My car has slightly over 1000 miles on it so I'm hoping as it approaches its 2500 mark the mpg will go up a little. It disappoints me to know my fathers Charges R/t destroys me and gets just as good mpg..

First road trip report... Detroit to Chicago (roughly 350 miles). I got 29.7 on the way in. Average speed through Michigan 80 - 85 and 70 through Indiana and Illinois. On the way home I got 31.9 doing 65 -75 the whole way because of snow and ice. Very very happy with those numbers. We have 3200 miles on it in the first month. The 2.4 is working out great for the wife, she has a 100+ mile roundtrip daily commute. She was driving a Commander and getting 15, now she averages 27-28.

Thanks for the updates guys!

Back down to 20.85 mpg today. Not suprising with the weather and all, and the idling in the garage warming up. The weather has been so up and down lately, and I haven't been as diligent in my pressure setting of my tires as well. When I got them rotated it seems they just randomly put more air in the front two for some odd reason, so when they are warm they run 36-37 and the ones in the back run 33-34.

Thinking of trying 35 or 36 psi all the way around next. Just haven't had the chance to do so.

I don't think you could have said this any better! My wife is guilty of this as well. She just doesn't understand anything about cars. Her life could be at jeopardy, as well as her passengers. Thanks for the tips though!

I've posted a couple times in different threads that I'm getting pretty bad gas milage, and to top it off, I ran out of gas the other day...

I got in the car, and the gas light was on...I asked my wife how long it had been on, she said since yesterday...Ran out on the way to work...We could go a week of so when the gas light came on in the last car...We only have a 3 mile commute...We coasted into the the gas station with the car stalled...

Since I don't put a lot of milage on, I'm not worried about the milage, but I kind of deep down wish I was seeing the numbers others are getting...:4-looney:

You also have to remember, some of the larger numbers that you are seeing here are highway driving. Since you are only going 3 miles to work, you are not staying at a constant speed. City driving is the worst on gas mileage. In my G6 I would get about 27-30 mpg on a 37 mile one way trip, and when I shortened my trip to 17 miles, I was getting about 20-21 mpg. Good luck with your problems though. ;)

I have an R/T FWD and i'm getting between 21 and 24.4 mpg.

I drive about 50 miles a day to/from work. 40 is highway and 10 city (varying 35-45). We also drive the avenger for most of our errands. I'd say i'm right in line with 50/50 city and highway. I'm happy with it, much better than 13-16.5 i get in my dakota!

It's finally snowing in the atlanta area, probably some freezing rain and sleet later tonight and tomorrow. I'll for sure be driving my 4x4 dakota tomorrow. I'll be leaving around 3:45am tomorrow instead of my usual 4:!5 am :)

I am curious as to what I would get on long highway trips.

Getting 21-24 city, 30 on the freeway. Of course that is with conservative driving. Just can't seem to keep my foot of that gas pedal.

I just put a K&N airfilter on my Avenger SXT 2.7L engine. I will let you know how much of a difference I feel(Performance) and see(MPG) When I changed out the paper filter I was pretty surprised at how dirty it was after just one month/3000 miles.

I did a 200 mile trip and didn't break into the 20's...Ahhh...Oh well, it's still better than the truck!!:4-looney:

18 in the city and 25 highway

I filled up friday. Saturday I did about 100 miles of traveling, I have half a tank left.

Whats the calculation? According to mine I'm getting an amazing 11MPG. It was a mix of highway and city. I tried Shell (regs gas thread had me interested) and apparently they blow. Exxon has given me the best gas mileage that I've noticed but this kind of drop off can't be right.

I had also just gotten my oil changed from the dealership.

Your method of calculating is flawed, not the Shell gas. 'About 100 miles' - 'half a tank left' :wow:

100 miles divided by 8.45 since the tank is 16.9. Unless thats not the calculation that comes out to about 11mpg.

I just put a K&N airfilter on my Avenger SXT 2.7L engine. I will let you know how much of a difference I feel(Performance) and see(MPG) When I changed out the paper filter I was pretty surprised at how dirty it was after just one month/3000 miles.
Ok after driving for a while with the K&N filter in it has more pickup.

100 miles divided by 8.45 since the tank is 16.9. Unless thats not the calculation that comes out to about 11mpg.

This would be true if you could trust the divisions on the fuel guage as being "accurate". Unfortunately, like most cars, you can't.

If you want a 100% accurate measurement, try this. Fill up all the way. Drive 100 miles. Fill up all the way and find out exactly how much gas you put in. Then do your calculations.

Just for comparisons sake I'll offer this example. One of my last tanks of gas was during this last snow storm that hit. This meant my car idled more warming it up and that I had slower than usual commutes of city/hwy driving. When my guage hit half way I looked at my mileage. I think I was somewhere in the 125 mile range. I proceeded to drive out the rest of the tank and hit right around or right over 300 miles for the tank. I probably could have made it to 320 if I wanted to push. Normally I'll get anywhere from 340-360 miles per tank. Thats 20 - 21 mpg. So that tank I got 18-19 mpg.

Then I filled up. Now the weather has improved and I haven't done much commuting. But I did do some hwy driving. Today I saw my guage at 3/4 full almost exactly. I looked at my mileage....and it was almost 125 miles. This would mean I would get 500 miles per tank which would equal 29 - 30 mpg. Now I would expect that if I continued to drive all hwy miles as I did this past weekend in good weather at a normal 70-80 mph pace. But I would be very short sighted to think that trend would actually continue based on my normal daily commute.

When trying to figure out gas mileage you have to take in all factors, and then try to make accurate and consistant comparisions. Weather, idling time, stop and go traffic, specific kind of gas, if you have a lead foot or not, tire pressure, where you gas comes from, octane, etc, all play a part in mpg.

I mean say you get 32 mpg on an all highway trip where you set the cruise at 80 mph the whole way. Then you come home and drive around the city like a madman, flooring and racing people from stoplight to stoplight. You aren't going to get 32 mpg. You might get 12 mpg. You might get 18. I don't know. But you can't make a good test out of that because its such a different test.

Now if you take that hwy trip and put 87 octance shell in, and then on the way back put 87 octane exxon in and you get 27 mpg instead of 32, and your speed and distance was relatively consistant....well thats a good comparision, and now you know that you are getting better mpg with shell than exxon.

Hope this helps. :)

100 miles divided by 8.45 since the tank is 16.9. Unless thats not the calculation that comes out to about 11mpg.

But you did say about 100 miles - could that be 90, or 110? That would make a difference.
Next time your tank is at the half way mark, and you are next to a gas station, pull in and fill it up. I'll bet it isn't close to 8.45 gallons. I'll bet it's closer to 10 than 8.45 - maybe even more than 10.

I'm certainly hoping as I get some miles on the car that my Avenger's mileage improves significantly. I picked my R/T up on the 20th, it hit 450 miles today and I'm already at a half a tank on my 3rd fill-up.

Just got home from the first long trip in my SXT. 1200 miles. I checked the mileage between the last two fillups (all interstate driving) and came up with 32 mpg. 2.4 engine. Best I could do with my RAM 1500 was about 15 mpg on the highway. I am a happy camper.

Randy

That's great news - I've also got the 2.4.
I haven't checked mine yet since I have been using the remote start quite a bit - I start it in the morning before I even get in the shower. Then again about 10 minutes before I leave the house. Then only drive about 4 miles to work. I probably burn more gas sitting in the drive way than I do going back and forth to work.
I also have the front seat bun toasters - on bitter cold mornings, it sure is nice.

Well I just took a four day trip, 1600+ miles and enjoyed every moment of it, (at least the way the car performed). I was worried that with only having the 4cly going up hills would be straining, but the car performed well. :smileup:
There were a few moments that I wished I had a few more horses, but I dropped down a gear and all was well.
I calculated my mileage, and got around 28mpg the entire trip, so I was happy.
I was well pleased with the avenger driving through two major snow drifts, only a couple of scary times, mostly my fault.

I was also leery of the 2.4 performance as it has been many many years since I drove a 4 cylinder car. And I was used to the 8 cyl in the Ram 1500 Hemi. I have been pleasantly surprised. In many reviews the reviewers complain about the 4 cyl engine, but I don't have lofty expectations I guess. I knew what I was getting and am happy to be getting much better gas mileage. 80% of my driving is around town and my Avenger does just fine, although I haven't done a mileage check on my average daily driving. I will report back when I do.

I agree. I went from the 2.0 Caliber to the 2.4 Avenger. The Caliber wasn't a total slug, but less than a half liter more in a car this much bigger? It suits me just fine.
I think the reviewers that complain are too short, and have trouble pushing the accelerator more than half way.

I think the Avenger gets such a rap because it looks so strong, and people expect it to be in the Charger range when it comes to performance< especially the R/T.

While I enjoy my Avenger and think it has plenty of get up and go, I recognize it is not a pure sports car. If I wanted the power, I would have gotten a Charger or waited for the new Challenger, and paid a lot more. If I wanted to get 40 MPG I would have got a Hybrid.

These reviewers need to look at exactly what the intended target is and go from there. I am pleased with my car, yet do not look for it to be something it is not.

I bought my R/T because it was more fun to drive than the SXT with 2.7. the fuel economy was not much different than the SXT and it gets A LOT better fuel economy than my 02 dakota quad cab 4x4 4.7L V8. If i were really concerned with fuel economy i would have gotten the 4 cylinder avenger or bought a non dodge.

Even at my low of 21-22 mpg my avenger R/T still gets 8+ mpg over my dakota.

45 week for gas instead of 80+ is good enough for me and I plan on having it for many years to come. Of course insurance is more, tags are more, but that would be the case with any brand new vehicle. Not to mention we drive the avenger most places now instead of my wife's 06 jetta, so she fills up maybe every 3-4 weeks - that's another savings right there.

Plus it's the 1st avenger R/T.

on a side note about insurance, if you have multiple vehicles for yourself or family, inquire about "pleasure class". Since my wife doesn't drive her car that much and I don't drive my truck that much, both are listed as pleasure class and the insurance rates are considerably cheaper.

- Dan M

Hey DM good tip. Thanks.

I have never thought about that Dan. What mile constraints do they have for the pleasure class?

Probably varies from company to company.

Also something else to think about is when they ask that question "how many miles to you drive per day", they usually follow it up with "to school or work".

The key there is the word "OR". If you take class and work, and its 5 miles to your class from home, but 40 miles to work from home, the correct answer to their question would be "5 miles". I beleive they use this to grade you as well, so it could mean lower rates.

Sometimes, they will trick you into stating something else later on. I recall once they called to ask a few questions and then threw that one in as a last question. They called it a survey or something. I answered to my work miles instead of my school miles, I was in a hurry to get off the phone but I was being nice because it was my insurance company and it was only like a 5 question "survey". Next month, I got a increase in my statement. So be weary.

Thanks for the info AvengerRT. I always wondered if they really used the mile question as a rate determination. Now I know they do! Also, if you car pool, tell them you car pool. You might be able to use you spouses, or whatever, as a 'pleasure' car. They may help out on insurance. I also am registered on my wifes car even though I don't drive it because it is a lower rate for her car, for me that is.

I believe what they are asking is what is your daily commute. To which the honest answer would be 40 miles.
So they are not trying to 'trick' you into stating something else later on. They are checking your honesty.
By telling them you drive 5 miles, when you know you drive 40 is analagous to telling them your car has an alarm, airbags, and that you always wear your seat belt, when in fact your car has no alarm, no airbags and you never wear your seat belt.

I'm not trying to be the insurance police or anything - I love low rates as much as anyone - but you want to be careful of what you are 'letting them believe.'

Well actually, if you read my post I believe I said they ask you the question with the word "or" in it. I'm not sure what definition of "or" you have, but in any case I guess we disagree.

I'm in no way defrauding, attempting to defraud, or suggesting anyone defraud their insurance company. I, in fact, have asked this question of the insurance at the time of their question, as to what it means and how I should answer. Their description and intent, was the same as what I said above.

It doesn't matter to me anymore, because I don't go to school anymore. So when asked I give them my one way commute mileage of 35. And thats ONE WAY. Thats how they ask it as well, so we can avoid any confusion.

Maybe we can start a new thread if we want to debate the merits of the insurance system. Because I don't think the length of your commute should factor in the cost of your insurance anyways. Factor in area you live in. Factor in tickets and accidents. I get that, but length of commute? Don't they say most accidents occur close to home? If so then why is my cost higher if I have a longer commute, shouldn't it be the other way around?

At any rate, like I said....maybe another thread.

Are you serious? The length of your commute shouldn't be factored in? I drive a pleasant 3 1/2 miles to work (one way). I used to drive 25 miles (one way)- on a busy highway, complete with stop and go bumper to bumper traffc. There is far less of a chance that some idiot will plow into me now.
Even without taking highway traffic into account, the more cars you see on the way to work, the higher the risk. That is just odds. And that makes sense. The more words I type, the higher the odds of a typo. The more lottery tickets you buy... well you get the idea.

What I really hate that they do is to use your credit score. Now that is just plain BS. I carry a higher balance on my credit cards around the holidays, and they raise my insurance. And then lower it again when I pay them off. What does THAT have to do with the odds of an accident, or theft, or anything?

...Don't they say most accidents occur close to home? If so then why is my cost higher if I have a longer commute, shouldn't it be the other way around?

Let's see: People living close to work drive close to home. People that live far from work drive close to home AND drive far from home - unless you teleport beyond that 'close to home' high risk area before continuing your drive to work.

And to keep (at least part of) this post on topic... I set the trip meter on my car the last time I filled up, and may check the mileage on the next fill up.:)

but doesn't statistics show most accidents happen close to home? This used to be the case, not sure anymore though.

Also keep in mind insurance companies rate in different ways and the policy price is affected differently. Check out difference companies and you may get rate difference of a few hundred dollars.

I mean, I've been with the same insurance company for over 14 years. Yes I do check rates. I used to check rates every 6-8 months, now it's more like every 12-15. I haven't found anyone close (closest has been around $200 more every 6 months). I get a lot of nice perks (discounts) from them as well.

- Dan M
Of course statistics show that. There is a much higher percentage of people that drive less than 25 miles to work than those that drive 50 miles. More that drive less than 50 than 100, etc. Again, the odds are high because the numbers are higher. On any given day, how many people are 200 miles away from home compared to how many are less than 200?
But at the same time. The longer your drive, the higher your risk is. Each additional intersection you go through increases the odds that you will be broadsided. Each stop you come to increases the odds that you will be rear-ended.

We are still off topic - sorry about that.

I guess what I was trying to get at is that the insurance companys do things all the time that can increase your rate. Of course they do it under the guise that it will make your insurance cheaper. But every little thing it seems is scrutized. Everything you do in life adds risk. Some risks seem necessary to me. If you live in a high crime area, if you work in a high crime area, etc. Some don't seem as necessary, ie length of commute.

Eventually the way we are headed, you will be rated differently if you drink water while driving, OWN a cell phone (even if you don't use it while driving), or simply if you state in a customer survey that you don't eat breakfast before you leave the house. Stupid stuff like that.

Credit scores arn't even the half of it. They already have a national database that records everything from tickets to accidents to claims, and I think the claims don't even have to be automobile related, just that you made some claim, that they can and will use to "grade" your policy. And it goes back forever. Then, they also will use how many other people in your house that are of driving age, even if they have their own insurance, and start asking you questions about their "claims". I had them once ask me about an accident my wife had years before I had met her. How the hell am I supposed to know about that? And what does it have to do with "my" insurance? Its getting a little crazy imho.

Luckily for me I've been with the same company for 10+ years and I'm grandfathered into the "old" system. If I wanted to go with the new system it would cost twice as much for the same coverage.

Back to gas mileage here... I have been driving my dads car around until mine gets here, and let me tell you... the gas mileage sucks on this car. It is a Mustang 4.6l V8. I have not calculated the actual mileage, but I am suspecting that it is in the neighborhood of 15-17 mpg, city.

When I was driving my G6 around, I was in the low 20's city, and high 20's
for highway. It was a 3.9l V6 though.

Of course statistics show that. There is a much higher percentage of people that drive less than 25 miles to work than those that drive 50 miles. More that drive less than 50 than 100, etc. Again, the odds are high because the numbers are higher.

We are still off topic - sorry about that.

I was referring to an old statistic i used to know but forgotten. It had to do with auto accidents and the proximity to home. I tried to do a quick search but didn't find it. I was wanting to say it was something like 60% of accidents happen within 5 miles of home. That was like 10 - 15 years ago though.

Got a K&N Air Filter and I went from 13 MPG on a tank to 14 MPG. Whoopie!!!!

238 miles on a full tank. Is this normal for the R/T or am I just out of my mind?

Kaiju54,
Is that city only driving or a mix of city/highway? I traded a PT Cruiser w/turbo for the Avenger and the PT never got better than 19 MPG.

Got a K&N Air Filter and I went from 13 MPG on a tank to 14 MPG. Whoopie!!!!

238 miles on a full tank. Is this normal for the R/T or am I just out of my mind?

That's very low. Give us some details, because there a a lot of variables that could cause that, or more than likely a combination of things - tire pressure, outside temperature, remote starting and warm up time, type of driving (city or highway) the way you drive, the speed you drive on the highway, the method you use to calculate mpg, etc.

I got 26.2 mpg on my last fill up in my R/T. Mixed driving including 1/2 tank in my daily normal routine. I used a little more than 1/4 tank driving around the north ga mountains doing some shopping in a few towns.

I think on a long highway trip driving 70-75 I could get near 30 mpg.

I normally avg 22-24.

all stock except I just changed my oil for the first time and put in castrol full synthetic. Same brand I run in my wife's jetta (it's the only brand that I can find for her jetta). That may or may not have had any effect on the mpg.

Its all city driving for the most part. I'd say 90% city.

Hi all.

Just finished a 5000+ km road trip, Saskatoon to Sudbury & back, and was paying close attention to mileage. This is all from recent memory. It'll all be in metric, but there's conversion sites out there. Metric mileage is in liters per hundred kilometers (the lower the number the better), stock '08 R/T. Temperature varied from around -4C daytime to -10C nightime. Someone bored with algebraic knowledge could figure mileage out for each speed range, but I can't be bothered. This was straight driving, about 3 hrs each way for sleep in segments & around 24 hrs driving time. Anyways, here goes.

Left Saskatoon with 15775 km on car, computer said 12.8 l/100k for gas mileage accumulated from when I bought it in September. I 'reset all' and in a bit it read around 10.8 from the reset. Cruise control set on 140k Saskatoon to Regina (reading around 10.3), set to 130 k/h from Regina to Ontario border (read less than 10), averaged around 115 k/h through Ontario (black ice + moose + tired from non-stop driving = zero cruise control). Hit Sudbury & computer was reading 9.5 l/100k. Coming back, cruise set to around 110 kph Sudbury to Sault Ste Marie, 105 from SSM to Nipigon (read 9.0 there, best mileage I saw). Nipigon to Manitoba border set cruise to around 115, read around 9.4. Manitoba border to 200K east of Regina cruise averaged around 125 kph, was reading a little over 10.

Around 200K east of Regina set cruise to 140. The mileage numbers took a big leap here, read around 11+ again. Interesting thing is that when the speed increased here I checked & computer read around 280K until empty. Drove around 100K & gas light came on & it said 57K until empty. An increase of 10 kph to 140 kph made me 'lose' 130 km somehow so it seems 140 (80 mph to southern neighbours) is the magic number if mileage prudence is a concern (personally, I didn't buy it for the mileage ratings). The gas mileage really starts to suck past 80 mph. Filled up around 70 km east of Regina & seeing as I only had around 350 km left, figured I'd be good until Stoon so didn't bother checking anymore. Arrived in Stoon with 1/4 tank though, cruising 140 still. I left Stoon Friday morning 10:10 & was back Monday night 11:45 so just wanted to get some zzzz's. Long trip.

I just bought my first tank of gas the other day. I think I got around 21mpg on 274 miles I think. Not too bad for the first 200 miles. I will keep you posted, as I always calculate mileages.

FINALLY!!!!! I finally got 19 mpg. I had to change my driving style a bit but finally. Lasted me Saturday to Saturday, 269 miles on 14 gallons. When I went to Queens on Saturday (I live on LI) I was getting about 25-27 MPG and then the rest of the week was all city driving. I noticed a lot of you don't excel past 45 mph so I decided to go that route since I would usually drive anywhere from 55-65 mph. The 14 mpg days are over!!!! I wish you guys could of saw my smile when I did the calculation. These boards rock!

Glad it is getting better for you! :)

I have the R/T AWD and I have gotten anywhere from 18.5 MPG to almost 24 MPG. I drive a considerable amount of which many miles are highway. It looks like I am going to end up around 21.5 MPG.

I pulled in nearly 340 miles in 14.2 gallons, majority highway driving around 75mph. I did use the remote start two times in conditions ranging from 11 degrees to 45 degrees, mostly flat road, and hauling around 2-3 full sized adults.

Can't complain.. my truck would have killed me on gas for that amount of driving.

i average about 21.9 on highway 28 mph rt fwd

I have been driveing from san Diego to LA for the past few weeks for some family business and I have averaged 28.9 MPG highway. normally I get 23-24 with mixed driving. Very happy with the 28.9.

I have a R/T and drive 40 miles each way to work driving 60-65 mph (mostly all higway) and get 19mpg with auto stick and 21-22 mpg if I use automatic.

I just hit 9,000 miles.

Hmm you should be getting more than that, is it stop and go on the freeway? Also there are tire pressure monitors inside the tires, so you don't need to manually check it :D

Yeah, I know. For the first 3 months I had just air in the tires and when I would check the air pressure it would never be the same as what the monitors in the tires read. The last 2 months I have nitrogen and it is exactly what my tire guage reads.

Also with air in the tires, I was always adding air. Since I put nitrogen in it, I haven't had to add any nitrogen.

Before somebody asks, It cost $6.50 /tire for nitrogen and if I need more it is free.

Just for my own knowledge.....what pressure are you running in the tires?

I just did a mpg for my car and in mixed driving with a bit of leadfootitis, I am achieving 27 mpg.

Just for my own knowledge.....what pressure are you running in the tires?

35 in front and 33 in rear

I tried 35 all the way around and 37 & 36 in front with 35 in rear and didn't like the way the R/T handeled.

It depends how and where I am driving I can get 29 mpg in my R/T setting the cruise at 72 mph with a fully loaded car. I can also get <16 mpg driving how I like to drive. It really just depends on how much I want to pay. I average around 20 mpg with very mixed driving conditions. The way I see it, I pay more to drive my fast car fast. This ain't grandma's car!

Hmm...ok then, thats pretty much what I'm doing right now as well. I usually keep all 4 the same but I've been too lazy to fill up the rears a bit. Weather is all over the place right now.

My last tank I dipped to 19.5 mpg, which isn't horrible, but I think it was the fault of my step children while I was in cabo....someone took a 4 mile joyride...and I'm guess they sat in it idling and playing with the mygig while I was gone as well...

lmao :)
Wonder how long they sat before they got the courage to take the joyride.

Me too lol. Its funny..I figured they would so I reset the second "b" trip meter to zero, just so I could see.

Not going to mention it to them though..just wanted to know lol.

I have a SXT Avenger with the 2.7L V6, I do a combination of driving in city and highway. I average around 26.5 mpg, if I get on the highway between 28-29 mpg.
This is exactly what I have and these are my mpg stats as well. The car loves the highway (I've gotten to 30mpg -- love the monitor on dash!), however, it's the city driving that drops my mpg to 24-26mpg. Car is getting broken in now at 7800 miles. I LOVE this car!!

I have an R/T AWD and have been getting 21.5 mpg with mixed driving during cold weather conditions. I drive 70 miles a day to and from work with about 30% being stop and go highway, 30% open highway, and 40% semi-rural roads. Normally, I do about 18.5 mpg city and 25 highway. I have gotten up to 28 mpg on flat highway, but not usual.

It only has about 1k miles on it, so it is still breaking in. I have been running 34 psi in the tires and will probably have them filled with nitrogen when I take them in for their first rotation.

My last tank of gas lasted until 334 miles before the low fuel light came on!! Big difference from the '05 Grand Cherokee 4.7l V-8 i just traded in!!

Well I am at 2200 miles now, and I am getting around 27 mpg. I drive it 17 miles on way to work, and I travel through two towns. So I would say it is a mix of City and mostly highway... I can't wait to start getting the good gas mileage though.

I own ths SXT 2.7 V6 and I run the standard E10 from the local pumps @ 87 octane and I am a bit heavy (cough cough) footed. I just took another 1800 mile trip with speeds above 70 mph and maintained 29 and 30 mpg. In normal day 2 day driving I maintain 27 mpg with a combo of highway and city with heavy stop and go hitting the Wash DC line every morning.

I've have the 2.7 and in a city/highway mix I'll get around 28MPG using E10 regular and with E85 it's around 21MPG. It's still braking in with only 4,300 miles.

I have an R/T AWD and have been getting 21.5 mpg with mixed driving during cold weather conditions. I drive 70 miles a day to and from work with about 30% being stop and go highway, 30% open highway, and 40% semi-rural roads. Normally, I do about 18.5 mpg city and 25 highway. I have gotten up to 28 mpg on flat highway, but not usual.

Thats in line with everything I've been seeing as well with my FWD R/T. As the weather gets warmer I think you will see another increase as well.

334 MILES on a tank of gas :4-dontknow: We are lucky to get 234 in our R/T
and that is about the same as what we got (234 miles) on a tank of gas in a
4 cyl. Mazda Tribute. city driving

Filled up the R/T yesterday 46.00 1st oil change tomorrow
My truck w/ a V8 62.00 in which I get about 340 miles to a tank

If the tires are low the indicator will let you no, if they are a little low I dont think
that's were your our gas is going.

I've played around with this quite extensively. Now maybe its due to break in, theres no way for me to quantify that. But if I run my tires at 30-32 psi all the way around (cold) I WILL get worse gas mileage. If I run them at 34-36 (cold) I WILL get better gas mileage.

Currently I am running them at about 34 or 35 psi cold. I think after they warm up, while checking with the evic they run at 36 or maybe 37 psi.

I got 21.65 mpg on my last tank, which is about 365 miles per tank. I suggest going no higher than about 350 if your pushing it...I ran completely out of gas at 360.1 miles lol.

I just filled up after running a complete tank of E-85. It got a little over 21MPG with a mix of 50/50 city/highway.

My 08 Avenger 3.5l now has 8800 miles on it. I have had as high as 31.6mpg for a tank during highway driving trip. Overall, the MPG is 24-25. My wife has a heavy foot. I can nurse it to higher specs.

If I use BP gas, I get 2+ mpg better. I've gotten as high as 27.5. On average, I get 24 using BP. I did alot of 75 mph driving last fill up and i got 23.8.

I have not tried chevron, texaco, citgo or conoco yet

I recently took a trip to Portland, OR., and got a best of 26 mpg. Lowest was 22 mpg. I did find that tire pressure had a noticeable effect. From Portland to Ashland, I got about 23 mpg. I filled up in Ashland, bumped tires from 32 to 36, and got 26 mpg between Ashland and Reno (which is basically an uphill run). Around town, we typically get 18 mpg, which is better than our '97 Safari van!
Anyhow, the car is a great traveling machine -comfortable, quiet, good handling, and good sound (we have the Boston Acoustics speakers).

I just started using E85 ($2.29 a gal.) in my 2.7 SXT, and I noticed i went from 19 to 16 mi/gal. I do a lot of city driving, and I have a K&N in the car. I think I should be getting better mileage than what I am getting with regular fuel. and the fact after only 4000 miles my other air cleaner looked like it had 10,000 miles on it all dirty and nasty. after only 700 miles with the K&N it is starting to look the same way. It gets the worst right around the stock inlet for the air box. Is this right? I don't think it is I have been around a lot of cars and engines (diesel mechanic military) and this is the wost I have ever seen as far as the rate at witch the filter get dirty

Thats why we have been modding the air box to help with the air distribution. I just filled up with E85 today and it was $2.80 vs $3.39 for regular, so your $2.29 is awesome. I did check the mileage since it was burning regular the past week and it got 29 MPG (mostly highway). In the past when burning/drinking E85 the highway mileage is 21-22 MPG and city is 18-19 MPG.

$ 100.00 pesos gasoline that are 14 liters (3.7 gallons) and only performance 55 km (34.18 miles) ..

Only 9.3 MPG :4-dontknow:

Please help me! :( My avenger is 2.4L only 637.66 miles .... Use the climate control moderately,only drive in the city, not use step 3000 RPM...

T

Yeah, mine is pretty bad too... not that bad, but it is in the very low 20's. I would say you need to get some more miles on that car, and then see where it goes. Do you have autostart? Are you using it much if you have it? That can play a large role on gas mileage...

i dont not have autostart.... My avenger Se 2.4 215/60R17, color black. in Villahermosa Tabasco, Mexico.

Only 9.3 MPG :4-dontknow:
T

9.3 MPG from a 2.4L engine is way too low. Take it to a dealer the O2 (Oxygen) sensor is probably bad/disconnected causing it to run very rich. My 2.7L running gas gets 28MPG and using E85 which run really rich is 21MPG your 2.4L should be in the 30+MPG range.

My 2.4.. all I can say is I love it, haha. Looks like a HEMI, runs like a Cobalt! Anyway, I don't have EVIC, but I would say I'm probably getting around 28mpg highway, and around 22mpg city.. I drive with a lead foot though. Actually, those numbers are completely made up but that's what I FEEL like I'm getting, haha. I never stopped to really figure it out because the mileage I'm getting is so great, I've only put a total of $40 of regular gas in the entire month I've had it. Up to 570 miles so far..

I know I have an R/T AWD, but my gas mileage has gone down alot... from 700 miles to 2,400 miles.... and power seems to have decreased a little, kinda worried about it i havn't done anything yet to it... I will be soon, Im thinking about a mandrel pipe and k/n filter.... I think I need to take it back and check it

Well I filled up yesterday and I am at 3300 miles on the Odometer... got 26mpg on 87 octane. I drive 68 miles a day to work and back. I am about 8-10 miles doing 75mph, and the rest is 55mph. So I am still waiting for the good gas mileage...

Do you have a K&N drop in air filter ? They do work very well and it will help with the mielage or get creative and do the home engineered CAI. I'm thinking of making a CAI for my 2.7 SXT.

It could be worse I just filled at $3.50 a gallon, my 02 Dakota Quad Cab with a 4.7V8 and it gets 13 MPG in city driving.:doh:

I have over 10,000 miles on mine. I bought it Oct 31st. I'm putting around 2k miles a month on mine. Since buying it I've put about 4k miles on my dakota and my wife has put on about 2000 miles on her jetta.

I'm still getting around 25 MPG in my avenger using BP mid grade. If i drive 70-75 on highway instead of 65, I get high 22 to high 23. I'm still noticing around +2mpg from bp midgrade.

I have not added anything performance wise to my car yet. I am planning on building a SRI, but I have to wait for more fundage to come in.

I'm spending my fundage on my dakota right now, making it more off-road capable.

thats the funny thing i just changed the oil at 2,3?? something and thats when the gas has started to kick me

Reaper what grade of oil did you use?, i read some where that thicker oil will add milage.

I have been running E85 in my car and I am getting 20-22 mpg. I drive it about 13 miles to work at about 55 mph average. The only downside is that I have to drive about 20 miles to get to the E85 station but luckily it is in the same direction as my job so not a real big lost, I am still saving some money on gas and Kansas has a tax credit if you report how much E85 gas you bought on your taxes as well as the credit for buying the E85 car.

Well i drive about 500 miles a week at least for school. On my way there the EVIC usually starts at 25.0 and eventually climbs to 30 MPG (with the wind behind me) and thats with the R/T. I usually get about 25.6 on the way back home against the wind. overall between city and highway i think it is right at about 21-22 average. I plan on adding a CAI and probably a new exhaust. Has anyone added a mod which gained some MPGs?

Not really, it stays around the same even after your ecu relearns everything. I think these cars are optimized from the factory now. :4-dontknow:

I live in the country and the county I live in is a rural county. No large cities, but I have an SXT and have been getting 27-28 mpg. I am really impressed with the amount of gas that I am saving since I have traded in my Durango and gotten the Avenger.

Do you have the 2.4, or the 2.7?

I am getting about 27-28 with my 2.4. I am only at 3000, so hopefully the number will go up some more still!

I have a 2.4 and just finished my first full tank (first tank I filled myself anyway) and came in just under 29mpg. little over 1000 miles on it right now (today was day 11, so i'm running it just under 100 miles a day), and I pulled about 490 miles out of that tank and the fill up was under 17 gallons ( I believe I have 18.8 tank) which means I should be able to squeeze 500-550 between fills. personally I wonder if I run at half a tank max if I will do any better (average weight while traveling will be 80 lbs lighter)

If it gets better after it's been run a few thousand I'll be happy with it. If I can get it up to 32 consistently in good weather I'll be thrilled

I am interested to see what you think later about the mileage.

25 MPG around town on my 1997 avenger 2.0 dohc 5 speed.

Based on my last 3 fills, I'm getting about 22.5mpg avg from my 2.7L.
Not the greatest for such a small displacement engine but certainly better than the 11.8mpg I squeezed out of my Dakota driving the same route to/from work.

I thought I would add this just in case: There are settings like defrost,Mix Mode,and floor mode that effect you gas mileage. If anyone is interested it's on page 196 in the owners manual.

Very nice read. My manual has now found a new home in the mag rack by the toilet. Got 27.5mpg on a trip that was half and half highway and city. Just refilled again and got 19mpg :158:. Yeah, this was my "kills" tank. Lots of agressive driving the last couple weeks. Got about 23mpg on a city tank back and forth to work and cruisin downtown. 2.4L SE by the way.

Nice! Sounds like you are doing well with it. What do you have your tire pressure at?
Running 34 pounds all they way around

My last 2 tanks post-install of my new exhaust (http://www.avengerforumz.com/showthread.php?t=39907) I have been averaging a little over 23MPG. After the current tank Ill be counting the seconds until I get a weekend warm enough to install the new ProZen CAI.

Im also hoping I can get the ProZen Airbox to go with it. Ill be reporting before/after MPG from that mod.

The next upgrades which I hope will improve MPG will be oil change and spark plugs.

I have an SXT, 2.4 and with the air on and the cruise set at 78, I'm getting a pretty consistant 32.9. Keep heaing a CAI will bring that up some. Wonder if that's real and if so, which one?

Went on a little vacation and @ 80-90MPH w/ cruise and A/C on blast I got 28MPG in my 2.4 2008.

On the way back 80-85 + traffic in Fort Worth was bad and did not use the A/C as much I got 31-32MPG.

hey guys i just went outside and checked my cars because im very concerned and being from canada i couldnt tell off the top of my head so i just went and checked my mpg and im at 15.0 seeing as you guys are getting 25-30 wtf is going on, i drive a little fast but not enough to justify 10-15mpg difference.
btw i drive an 08 r/t FWD

Don't feel too bad Tyrant. My last 2 tanks were 13.3mpg and 14.7mpg respectively. I too have an '08 R/T. I'm guessing it's the winter gas along with the weather that's causing it. ALL my driving is town driving and it's only ~3 miles to work so the car barely warms up. I'm guessing the people with the 3.5L that get the good mileage do mostly highway driving. I know I can get 27mpg to 30.7mpg on tanks that are pure highway. Do you do mostly town driving? During the non-winter months, I get anywhere from 15-17mpg with my town driving.

Damn people I really feel for you..I average 26-27.5 (EVIC). Got 31 all hwy... Could be better.

Most the high mpg I believe you are referring to are 2.4L 4 cylinder cars, and probaly more highway than city.

@70mph road trip I pulled 34.1 in my 2.4. That was only 2 rest stops in 400miles.

I've also noticed that my millage has dropped to around 26 since the start of winter. Normally runs 28-30 during the warmer months.

The 2.4l on paper should get a lot better gas millage. However according to the forum results the 3.5l and 2.7l get almost the same mileage.

The big reason is that the 4 speed transmission in the 2.4l is very inefficient. I am often in a high RPM waiting for the next gear.

The 6 speed transmission is a lot better at keeping the RPM's down and thus results in almost the same gas mileage. Wish I had known this when we bought the 2.4l.

Additionally you will see a bit of a drop in winter gas, thank you EPA!

Wow I cannot believe what you guys are getting... i calculated mine numerous of times and i get average of 14.7 in the city... Its hard to calculate highway miles because u would need to use a whole take, knowing you get different gas mileage depending on what ur fuel level is at...

My 2011 Heat consistantly does 28-30 open road with cruise on ~72

Two biggest reasons for drop in gas mileage right now would be the crappy Ethanol that they add during winter months, and the snow tires (particularly, if studded). Far more drag with the snow tires, and that will be a big impact on fuel economy. And then add in the "winter blend" on the gas, and I've personally dropped from about 30mpg highway to about 24. This is with an 08 R/T. Depending on your tires and who's refining your gas, you could get worse than this (or better, I guess).

LOL....actually I don't have a clue....all I know the employees at the local gas station don't know my name....so that must be a good sign.....

totally agree with that. i got my Avenger for the better mileage than my Dakota and it does, but im hoping to get it back up to 30 on the highway, right now its closer to 24-25

there is a station in town that has a nice big sign up that says "Ethanol free gas" but its a local oil company that makes it, not sure i trust it, but id rather have ethanol free gas. would it be bad for an engine that is flex fuel capable?

Mine is a 2.4 W/ 6 speed and it also kinda lingers in gear before a little bit. Kinda annoying sometimes. After a idk a semi fast jump from a stop light 2-3 gear feels like I either have to let off the gas completely or keep it floored to get it to shift.

Idk Just kinda feels weird. But I think its just me. My last car was a altima with a CVT tranny. So I got kinda used to a super smooth accel..

our old murano had that cvt tranny, it took a little to get used to, but once you did, it was cool

that 6 speed has a tight gear ratio between 2 and 3. its almost like 3rd gear is more like a 2.5 gear :) when it changes, the RPMs drop less than 500, its a real close gearing

Nice Find midnight!! That's why we get such horrible city mileage..

This kickdown gear ratio also "technically" makes it a 7-speed auto. :)

true!! :smiley_thumbs_up:

Last week on my Christmas Day six hour round trip drive I got 24 MPG going out and 32 MPG coming back. The big difference was that I was primarily driving uphill one way and downhill the other.

What a difference.
