CaliGrrl has a good point. This interests me because the only ethanol free gas around is usually 91 octane. Last summer was my first with my 06 Ninja 250, and only ran 93 octane with ethanol, though I usually added a fuel treatment. But... since I never tried 87 or 89 octane, or ethanol free, I don't know if I experienced dimished performance with 93 octane or not.
