My manual for a 15 is the same as Steve's, 86. The myth: Higher octane rating equals higher grade of gas. Most people who know more than me agree that is not true but is still appears to be a belief of many.

Honestly it may not matter on most newer fuel injected vehicles, however my personal experience has been better performance with higher octane ratings on my older vehicles. I'm more brand specific for the same reason as I've had issues with many of the off brand fuels. Mostly your paying for the additives at this point. If I remember correctly most fuels are mixed from the same base gas, only a few suppliers own the whole chain. Amaco was one of them. I've gotten the best/most consistent performance from Chevron and Conoco. Conoco's are few and far between on the West Cost so Chevron is my station of choice. The extra price is worth it to me for the piece of mind it brings. Just my .02...or .25 if I'm at the pumpOriginally Posted by 2wheelsforme
