But yes, at lower speeds and through town having the windows down will be more fuel-effecient than having the A/C on.

well i get 240-260 miles on a tank which is about 13.5-16 mpg and its all right but i have an safc2 and cone filter and 3" exhaust with a 2.5" header not to mention im rolling on mitsubishi evo 8 wheels with 245-45-17 falken azenis with a small spacer and only with a small spacer will it fit. does anyone have a safc2 on their car cause i need to know why mine wont read throttle postion, on either settings arrow pointing up and right or the arrow pointing down and right so i have it set to doulble asterisks and any tuning tips like high throttle settings would be nice

premix with penzoil semi synthetic (walmart) 12 oz per fill of around 15 gallons.
u can get around 130 mpg from a regular car, can't remember where I read it, but all you have to do is speed up to 50 mph and shut the engine off and glide till if stops and keep repeating.
offcource I am JOKING pls do not try this as it is very dangerous, yada yada...
