I am around 28mpg most the time. That is all city driving. When I drive all highway I usually average in the high 30s/gal.

 

Iget about 28/30 mixed and 34/36 highway. Only mods are cai with k&n filter, the car is a mtx also.

 

All city driving and backroads for me... 04 SXT auto andI get 28-30 mpg as well. Just have the CAI, cat back exhaust and 17' rims? Run the 89 octane almost all the time then once in a great while I'll throw in a tank full of 93... Don't think I ever noticed any difference besidescosting more!!! LMAO

 

On a full tank I can average 320-350 miles. It really depends though, on whether I am driving straight through or stopping and driving, or merging onto different highways. I know my air filter needs changed, and so do my spark plugs, so I'm sure I could get a little better mileage once that's done.

 

Well we got back from Myrtle Beach yesterday. All around trip got me 34 MPG. There was one part of the trip when I filled up in Virginia and refilled about 45 minutes outside of Myrtle when I hit 38 MPG. Still not too bad considering I was driving through the mountains and also running between 75-80 MPH at times. Not the best for fuel efficiency. But all in all I'm happy with what I got out of it. Oh yeah, I also run 87 octane all the time.
