Unless your doing it in a lab type enviroment, there are way to many variables which could influence your actual MPG
Well, actually I had been putting 87 in it all along, then went to 91 for one tank.

The only reason I asked this question is because in some of the past threads about gas mileage a lot of people claimed that using regular will get you worse mileage...and from my experiences (at least so far) this is incorrect.

As for the people who are getting 13MPG in these cars...what in God's name are you doing to them to get that poor of mileage? I believe the factory rating is 20/26...unless you're driving it like a ricer (that is, redlining it through every gear every time) you should at least see 17-18MPG.

I'd be pissed if I got less than 19MPG...but that's just me.
