We all know that winter blend fuel affects gas mileage, performance, etc. If you don't know that yet, then do NOT start a war about it in my thread...there are dozens of these posts on the forum, use Google.

Anyway, someone linked a page that had cycles or something of which months get what blend of fuel or something along those lines. Does anyone know if Feb/March is the absolute worse? I randomly went from an indicated 24mpg in Nov/Dec/Jan to freaking 22 in February and not I'll be damned if it doesn't say 21.2 and refuse to get any better.

Daily commute Mon-Fri is 62 miles. 31 to work and 31 back. First 4 miles is backroad (several start and stop, braking/accelerating, slow speeds) then 8 miles of small highway driving through 3 towns with occasional red lights, slowing and stopping/accelerating, sometimes a school bus, etc) then the rest is interstate 322 where I'm at 65-80mph steady for 19 or so miles. At least 60% highway 40% city driving and I'm getting worse than the "average" city MPG right now. Haven't been hammering down and driving spirited at all lately, been doing the entire commute multiple days a week without going above 3psi of boost once or twice at best. Wtf is going on?

I understand the following:
Performance car
Stage 3 with tune
Bad handling winter tires

But really? 21.2 with all that highway? lol

But I am catless stage 3 and tuned on 93 octane. Throughout this winter I have gotten around 20-22 mpg city and about 30-36 highway. But I noticed a drastic difference in mpg between 70-80mph. The faster you go the worse it is of course. But in these cars it makes a huge difference as well

Dude now that Miff Sheetz has flex fuel I need to just stop being a b**tch and just get the e30 strat tune and run 93/e85. I HATE, and I mean HATE, Sheetz fuel...it's awful because apparently their pump design sucks, but if I'm putting e85 in it I'm positive it'll fix that issue.

I have no complaints. I had even got a revision from strat and my lowest negative correction before the tune was -1 now i get zero negative corrections and the car pulls hard up to about 6100 rpm then falls on its face.
