Octane Type

[Hubes]

i notice that my car runs better with higher octanes so lately i have been putting in higher octane gas. perhaps it is a placebo effect and in my mind, but i like it.

My SHO will ping under a slight load running 89, and I can't afford burnt valves, so I just run 92 or 93, whatever's available. It never pings on high octane, and to me it's worth the extra $1.50 if I can avoid burnt valves.

My '97 got the 14.609/95.13 on 87 octane and 10% ethanol.

Speaking of fuel..... does the Brand or type (station) really matter and do the ones that claim to clean really do so?? You all seemed knowledgeable on this topic and I have always wondered if the name brands were different than the corner Bob station. I remember as a younger driver, I always went to Shell becuase my Dad said so, the gas is better, or cleaner he said. Just thought I would ask
