Ran 100 octane for the first time. Wow

I hate to ruin the illusion, but your car did not run any better because of the higher octane...it ran smoother because of A-The purity of the gas, B-The lack of ethanol.
The octane rating of a fuel only indicates its resistance to detonation. If your car is timed and jetted to run on 87, and all you do is pour 100 in the tank, there will be zero difference in performance. If you go further, to 105 and better, you'll actually see a decrease in performance and mileage because the fuel will be too slow burning for the lower octane settings.

Awe MAN....I was having fun watching this post go way off the track, and there you go, having to breath some sanity back into it, lol.

I agree, if your motor does not have the compression to require higher octane fuel, you will actually run slower with a fuel that has a slower burn rate (e.g. the higher the octane rating, the slower the burn rate).

I like to have the ethanol content of my fuel to be high....like 85% high.....:D. My last tank of e85 cost me 22 dollars, and the tank was near empty (only $2.50/gal)...:cheers:
