102 I think is race gas... seen that more than 97... and all over... but again... too wide spread to rely on filling up with it every tank

Weird, because I live in CA, and the highest I've ever seen here is 91.

93 octane. In MI you have a choice of 87,89, or 93.

weird... cause I could have sworn I saw it on past Sacramento going towards the bay... maybe vacaville?.... could be wrong though...

I do remember it was in Cali... cause there were a few vets and a couple Ferrari's at the station... maybe it was near Berkley.

When i lived in Iowa there was a gas station near us that had 110 octane race fuel at the pump. It wasn't right next to a race track either.

While it is true that burning fuel with a higher octane number alone will not generate more power and may actually reduce power, that isn't the only factor. Some of the higher octane "race gas" available is also oxygenated. Sport Rider magazine conducted a fuel study a number of years ago and found that the higher octane oxygenated fuels generated more power on the dyno than regular gas.

Near Des Moines? I know there was a station there that had over 100 octane, can't remember exactly what though.
