Brand of gasoline

For the Boxster, I try to get Mobil, BP or Shell. During the TOD trip, I used a lot of Chevron, and liked the fact that you get the Techron additive with the 93 octane.

For my wife's MB I do the about the same as above.

For the Company Explorer XLT...it gets what ever is convenient.

Overall, I go to stations that are very busy and "turn" their fuel over quickly. I think this is actually more important than actual brand. Fresh fuel...just like milk and bread!
