Mar 09, 2021· The 80 hp 912 A/F/UL is good with regular. I’m fortunate to have a Stewart Ice Cream Store, near my airport, that carry’s 91 octane non ethanol fuel, at decent prices. I only use 100LL on cross country’s and mix in some in the winter, as the 100LL shelf life is longer. Ethanol up to 10% is not a problem for Rotax.
