I'm going to respectfully insert a note here to remind everyone. Octane rating is NOT a measure of power! Higher octane means the fuel is more resistant to ignition under extremes of temperature and pressure (pre-ignition) and, it actually burns "slower" - does not "explode".

Southpaw, I was not taking anything away from your absolutely correct post. I just get "twitchy" when I hear anything about hi-octane fuel.
