use BP gas for performace?

I wish I could find somewhere else within a few miles of my house that sold 93. All I can seem to find is Shell. I haven't had any bad experiences since I've started using a different (read newer) station, but I hear a lot of people have had trouble with Shell gas. But I don't want to go back to 91.

Slightly off topic.... did you notice in that Top Tier list that there's a QuikTrip AND a Kwik Trip? How in the world did THAT get by without a lawsuit??? Surely they're not owned by the same parent company... what would be the point in changing the spelling?
