also with the facts... that higher octane does not incress power, only reduces detonation. well that would be half true... because my car (with 9.5:1 compression) DOES have more power with 93 as oposed to 87. this is because (im my best guess) with 93 reducing detonation, my timing stays advanced as where with 87 my timing gets retarded alittle. there for in any vehicle where the timing is being retard by even the smalled amont of detonation, higher octane fuel will incress power. up to the point where all detonation is eliminated. if all detonation is eliminated with 93 octane, then 100 octane isn't going to up any performance.
