Hey there AO3,
I googled this subject a couple weeks ago and found conflicting info. Everything I read agreed that cleaner fuel (high octane) provides better performance, but alot of the info suggested that the octane rating had to match the dynamics of the engine. Mainly too high octane could actualy reduce performance, not real sure how, but thats what i read. When i owned a 97 supra, a local tech/tuner guy told me to be careful, saying that high compression engines + race fuel (100+ octane) could equal holes being burnt in the pistons. The supra was a 9.5:1 and our F's are 10.28:1 I believe. A local station here sales 100 octane too, I'm thinking of trying 2 gallons added to a tank of 93 octane just to see.
