God DAMN...
$2.36 for 93octane here in maine...

Good advice with the writing your mileage out on your reciepts..
I keep a little book in my glovebox for that type of stuff, along with oil changes and purchased parts, etc.

BigT,
I could be way off on this one,since i'm pretty new to all of this myself... but maybe you could a) recheck the spark plugs if you feel like your mileage dropped.. maybe yur not firing off on all 4? Just a guess...

also, i've had someone fix the alignment on a previous car, and he just made it worse... so maybe that's something to think about as well?

Just trying to toss out possible ideas!
