what octane is recomended

[Kershaw]

i run 93 exclusively on my rx8. and i try to run chevron exclusively as well. but i was sent a notice that chevron/texaco is pulling out of my state. im so pissed.

i run 87 chevron in my e30. but im not that pressed if a bp is around the corner and is cheaper that i wont go to it.

chevron is where its at.

Glad to see I'm not the only one who prefers chevron! People always tell me I'm crazy! I've been having some hesitation problems and I wonder what if my car would run better with the stock chip and 87 fuel.

Anybody using additives regularly?
