Ok, so I'm seeing normal MPG's then? Just wondering because I got my wrx in November, and haven't seen what kind of MPG's it gets in warmer weather. Best I've got was 23 MPG, and ironically enough, it was on the tank that I burned up the day I had Nuke do a "stage 1" tune on the car, and I beat it pretty good after that tune lol. Besides the tune, and the Magnaflow muffler, my car couldn't be more stock.
Not a 2.5, but I'm seeing the same <20mpgs after letting my car idle so much this past week. Completely worth it though!
Got around to doing maths on the last couple fills. Still no issues with hard starts, lucky to see 17 mpg though.
Yeah, I just filled up last night and got 16 mpg. I'd say that's probably acceptable considering the amount of time my 860cc injectors spent idling at ~1600 rpms this past week in negative temperatures.
