100-120 miles on a full tank of gas!!! WTH??

im only getting about 100 to 120 miles to a full tank of gas! anyone else having this problem? My car is stock btw. I dont get on it to much and when i do its not for long. I bought the car for the power and ok gas mileage. If i would have known the car only got 100 to 120 on a ful tank i would have never bought it, any help? and what am i sup to be getting on a full tank? 250 miles or more?

You have to be staying in boost the ENTIRE time. From light to light redlining.

I averaged about 220 or 230 per tank. Maybe you are running VERY rich? Or maybe there is a leak? Or do you just like to hit the gas lol?

Could be running very rich, might need a tune, but it is stock so i dont know why it would. Im waiting on the parts to get here so i can do a boost leak test, but could a leak really make my gas mileage that bad?

your an idiot buying a Evo for GAS mileage was where you went wrong! you should have had a reason like loving one of the most powerful 4 cylinder engines on the planet as a reason to buy the car not gas mileage...but anyway something is wrong you should be getting more then that there a alot of things that rob gas mileage tho...old oil, how much u use the AC, air filter being dirty as *****, and the biggest of them all is Boosting it will burn gas like nothing..more air needs more fuel didnt mean to be a d*ck in the start of this post either im just saying

Dont ever buy any performance orientated car for "OK" gas mileage ..... Maybe a tune and or a tune up could help a bit,Either way it will never be amazing......

You should definitely have better gas mileage than that. I recently drove from San Diego to LA and back on the same tank of gas! 314 miles! I never used boost the entire time though. In any case, take it to a dealer or reputable shop to get it checked out. It could be bad plugs, air filter, overly rich tune, o2 sensor, and much more.

Yeah I get 210-250 (mostly stock) even when I get in it. Something really has to be wrong to get that terrible of a range. I have a k&n drop in panel filter and I run non-ethanol 93 octane. So I get slightly better than stock. Try those after you get it fixed!
