hey guys, have a quick question. I stored my car for the winter this year, about 3 months. Now that I have started using it again, I have been getting horrible gas mileage, like 15-18mpg. I used to get around 20-22mpg before I stored the car. Any suggestions on why this is happening and how to fix it?

 

Are you still on the same tank of gas from 3 months ago?

 

Winter gas is oxygenated (will get lower MPG) run to empty, refill with summer blend.

 

Man i wish i got 20 mpg.

 

U can also run a tank of fuel system cleaner such as Seafoam (found at NAPA) or Chevron w/ Techron. GL!

 

no, i've been driving the car for a month now, prolly filled up 4 times, i was gonna try fuel system cleaner

 

sounds like normal gas millage to me
for the 60k miles i had my evo my lifetime average gas millage is 17mpg. if i run it hard i can get 15mpg and if i never see boost i might get 19mpg. The evo is a sub 200mpg car and all the evo owners i know also get about 15-18mpg on average

 

Try to seafoam the motor , worked for me !
(I know this is a evo thread lol)

 

Ur lucky if you get 20mpg. After installing the WORKS brainflash it got a bit better but nothing spectacular. Who buys an evo and worries abt gas mileage anyway?

 

i was happy to note 21.03 mpg on one tank (all highway) on my way from indy to tampa over the weekend. i was like "awesome!, 21 mpg" and my gf just kinda looked at me funny

 

want better gas mileage? keep your fo0t out of the pedal! haha. we but all know how impossible that is

 

26.8mpg on my last tank with majority being highway miles.

 

^That's freaking nuts!! I drove my Evo very slowly and still MAY have managed 21MPG if I was lucky.

 

I was stock w/ no mods when I achieve that...now I have freer flowing intake, exhaust & tune, so I'm interested in seeing if it gets better or worse.

Basically I do 65mph on the highway and put it in neutral to coast down hills. Slow acceleration and be mindful of stop lights, stop signs where I'll have to stop....I coast up to them and try to time the light turning to green so I don't have to come to a complete stop. GL!

 

i got the 21-22mpg driving a mix of highway and street for almost 2 years but this is just bad now
