Fuse lit....
That helps immensely. Thank you very much. Where I live, I have 2 choices. 90 octane ethanol free, or 93 octane premium that could contain up to 10% ethanol. I guess 93 premium it is.
If those were my two choices I would use the 90 AKI. The owners manual says use 89 AKI and given the choice between meeting that with ethanol or without, I'd choose without. Around here where I live, there's no gas available other than at a few marinas that have no ethanol. 89 AKI (US rating) is equivalent to 95 RON. My choices are 89 or 93 AKI and I haven't seen any difference in mileage or performance (on my butt dyno) with either choice.
