I thought the hemi was spose to do good on gas. In town I average between 8.8 and 10mpg. Highway is about 12-15. is that right? or do i have some kinda problem. Yes i can say im "slightly" leadfooted but i dont think it would be that big of a change.

well i have a 05 quad cab 3.92 hemi auto..that i get around 13.0 in town and around 17.5( window stickers says 14 town 18 highway) driving my areas 65mph limit....even when im lead footed i cant get it to go that low...maybe you should have your dealer take a look at it.

 

oh yeah....the Hemi's claim to fame is being "good on gas".

since you offer no vehicle info....it makes it a little difficult to make suggestions.

plus...you are 17 and have "racer" in your forum ID.

so...that's the way it is.

 

If you are concerned about gas mileage, don't buy a 345 HP V8 truck. DUH

 

The Hemi's a lot of things, but good on gas isn't one of them. 8 is a little low, but not far from where mine was when new. Get some miles on it, go to syn oil, put a K&N in and lighten up on the throttle and it'll get better, but nobody with any common sense ever bought one of these things for the mileage.

 

When I bought My 05' 1500 I was getting around 13.8mpg and then it upped to around 14 and has stuck there for the longest time and now that Ive added a few mods its up to around 15.8-16.2mpg and thats driving rush hour traffic everyday monday through friday and around town. I think Ive gotten it as low as 11 before but that was when I was really gunning it seeing what it could do. But 8-10 seems a little low.........

Also I did buy my truck for the gas mileage mainly because my old truck was a 76' chevy short bed truck that I had tuned and retuned to the point where it had roughly 380rwhp and over 400lbs of torque which in return gave me between 6-8mpg and when you only have a 16 gallon gas tank your basically filling it up at least twice a week and it was just breaking my wallet

 

My '06 1500 quad CAN get 16.9 hwy with the 3.92 axle.
That is when I set the cruise at 65, and drive nice and easy.

Most of the time it lingers around 15.4

 

Good on gas? [sm=smarty.gif]
Dont know where you got that from.
I average 13 city 17 highway.
Being leadfooted does make a huge difference.
Big tires? Low tire pressure? Clogged air filter?
Alot of factors have effect on gas mileage,
but dont expect good mileage by any means.

 

haha racer came from my kart racing, which hopefully ill b able to get back into this summer. Umm Vehicle info...I have an 03' Hemi with 3.92 gears. Im not that lead footed. yea ill mess around every so often but I dont think I would be getting as low as 8.8 around town. I'll have to check it out because nothing seems wrong with it.
