I thought it was Che who posted saying 87 is better mpg then 90+.

as i said in my post, that hasn't been my experience. it always seemed to get better mpg with the 90+, but i figured it might just be driving conditions. then i had the chance to drive the 9ish hours from albany, ny to sandusky, oh (woohoo cedar point) and the 90+ got much better mpg than the 87. it was ALL highway miles with the cruise on so i figure that's as close to a scientific test as you're gonna get.

maybe my jerk-umption was wrong though. i guess people should find out what works for their own car. if the car isn't running well it's going to get poor mpg no matter what octane you put in there also.

I just discoverd about premium being 91 out here. Kinda dissappointed but the car seems to be doing fine. You shouldn't have a problem either.

nope...I turned the boost back up last night....I think the altitude is killing me...slow, slow, slow spool

Haha yeah I have to deal with the Altitude up here, and expensive gas prices. But the car seems fine for now. We shall see. After all it is a Volvo, they love to go wrong when you least need it.
