What kind of gas mileage would the 1994 trans am in my sig get in the city/highway without my foot in it all the time?? I'm just curious about it because gas prices will be skyrocketing this summer!

 

No way to intelligently guess without knowing the transmission.

 

Automatic

 

I get 21 mixed highway/city

 

what is the best rpm to shift at in an M6 to get the best mileage?

 

Keep the RPM's as low as possible for best gas mileage in an M6.

You should get about 25-27 highway with a A4, i get 31 with my M6 and a mild cam.

 

Yeah keep your revs between 1500-2000 RPM while cruising. I get about 17/29 city/hwy.

 

Getting just under 17.5 with 3/4 highway driving.

I'm 18 and got the car two and a half weeks ago, for as far as how often I put my foot in it...

Seafoaming it now, doubt there will be a change though.

 

BTW, that 31 mpg is w/ the cruise set at 70 from point A to point B. I get about 10-15 in the city the way i drive.

 

mods in sig, driving it like I stole it just about every time I drive it (its my daily driver and I rack up 2000 miles a month, so alot) I get about 16 mpg. its never been below 16, though. Even when I took it to the drags. My best tank pre-gears was 19 with alot of highway miles. thats with 80 mph cruising speeds at 2000 rpm.

 

I get 130 to a tank, thats with new o2s

 

you got issues man. I get 130 before the needle budges the full mark.

 

I'm at 120 miles and fuel guage is exactly at half. I dont think thats too bad

 

that 15% tint should knock you to about 10mpg in my opinion

 

yeah i get 150 a tank too, beats me to whats the prob.
