What kind of gas mileage is everyone getting?

[DaveL]

Before my trans and intake manifold went in I got around 15-16 miles to the gallon now I'm getting 13 with mostly highway miles! I just wanted to see if my car needs tweeking or if it's the norm.

yeah.....got some basic bolt-ons, just redid my exhaust with flow-tech from the headers on back...shortly thereafter did a full tune up and when all was said and done...i have gone from 200 miles on a tank to 230 miles on regular pump gas. so....its not super but i am happy with the improvement

165 miles/tank. mostly highway, 93 octane. mods in sig. car needs a tune, but I know it won't help much.

 

[ill advised]

Yeah, that's pretty low. I get around 16.5 city/highway in my modded Stang.

o/r h-pipe, flowmasters, underdrive pulleys, throttle body, cold air intake, and a couple other lil bolt ons havnt takin my mpg down, i still get 18-23 mpg in my 88 gt 5.0

 

[DropTopR]

WOOHOO! My car gets 14mpg, if I'm lucky. If it's straight highway though, I can knock down ALMOST 20. Gotta love .50 overdrives.

 

[ECU5.0]

i get around 18-20 on the highway. usually around 200 miles per tank.

 

[bhuff30]

I have been getting ~300 miles to the tank, which ends up as 22mpg... all CITY.
Oh yeah, I have a 4cyl.

 

[wisconsinboy]

15-17mpg

 

[cevtv]

I'm getting around 18 mpg, mixed city/highway.

 

[5spd GT]

I calculated mine and it was 23 mpg on one tank...drove it like a granny...and half of that is city driving...I really don't think I got that good though...I think my odometer reads wrong or something...
