naww, they're all pretty much the same. Especially now that they all pretty much added that Techron type stuff that Chevron first came out with. Just stick with the better brands and avoid the cheapy stuff and you should be fine. If any one brand is better, it wouldn't be by any noticeable amount. I choose Chevron basically b/c the gas stations are much cleaner than the others in general. I know the Bay Area seems to like Shell for some reason. It'll be like 10 cents more expensive than the other brands but people still flock to the Shell stations.
I tried Shell -- found a very slight difference from Chevron's, but it was negative (about .5-.75 MPG less overall). I then tried 76... I hit the freeway, and my car made a light 'clunk' and I lost a decent (10% or so) amount of power, which I didn't get back 'till I filled up at Chevron again (no 'clunk', but I felt it immediately when the Chevron hit the engine). I wouldn't touch Arco even if my car were about to die, Mobil's a little better, but that's not saying much.
for real 91 octane is the highest? i thought that might be in some rural areas but you guys are in big cities.
ive always put 93, i never knew that other cities had differnent octanes
:dunno: any reason?
