No boosting? Why did you buy an Evo?

 

I get around 180mpg on E85 with 1680cc injectors ~11 gallons
mostly city and I work about 15miles round trip from home.
It's the way people drive that makes the difference in fuel economy. I try to stay out of WOT most of the time, usually around ~5-10 psi max

 

Actually if boosting and tuned with stock injectors, you should get better gas mileage... No black **** out the back = money saved...

 

i save the boosting for the weekends lol........i have a 75 mile round trip commute everyday........I live in NY and work in NJ so i try to get the most mpg i can, plus i have a routine of always ending up having to fill up in NJ.

 

hmm, when ever i fill up i usually get 11-12 gallons which will give me about 250miles. But i also tried to top it off to the point where u see the gas lol and sometimes i miss calculate and i overfill which i hate because i have to wipe and my car smells like gasoline. anyways when i do this avg i get is about 290-300 most highway miles. Most i ever got in a full tank filled to the fullest is 330 till no more bars Im not tuned or anything either stock.

 

This is a nice thread to hear different peoples results.
However,
The OP is wondering why his mileage changed so much when his driving has style has stayed pretty mush the same, and if the fuel line is the result.
My advice would be to get a tune. That should iron out the problem. Plus thats how the car should be in the first place...
