Octane booster does nothing...it says up to 10 POINTS on the bottle. Read the fine print, 10 points= roughly 1 octane point so you're going from shit 87 octane to shit 88 octane. Just go get some race gas at your local track if you want higher octane. Airplane gas is NOT THE SAME as gasoline, it burns much much slower and is not explosive, i wouldn't run it in a honda.
