Yes, that's the understanding that I've had for years is that the little bottle of NOS octane booster you can get at the auto parts store is really just toluene. I think the fuel injector cleaner is really kerosene too.... Never done it because I've never really seen the need. Why would a higher octane give you more power? 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.
