Isn't octane just a measure of the anti-detonation characteristics of the gas? Your car needs at least 91 octane gas so that it won't detonate with the 11:1 compression ratio it has (high performance engine). If you ran 93 octane gas (available in some states, but not Cali) would you think you'd see a performance increase? I don't think it would be anything significant, just less of a propensity to detonate or knock. My two cents, for what it's worth.

Actually I thought it was other way around: These engines are made for 93oct, but they run with min of 91oct with performance decrease.

Am I right??
