I have 100LL, 93/93 Autogas (10% ethanol), and 91 Mogas (no ethanol) in my area. Please rate from best to worst for use in the Rotax 914.

91 no ethanol, 91 or higher with ethanol, 100LL is not a good choice at all because of the extra maint. Cost and leading it causes. Either of the first two are good choices and the Rotax engine doesn't care about the ethanol, but make sure your fuel tanks are okay with ethanol.

Roger,
Would you comment on 80 HP UL fuel. I have always used hi test mogas, 91
octane,( except when cross country flying and have to use 100LL).
Would I be better off with a lower octane rated fuel?

The UL can use 87 octane all day long. no need for 91 oct. with the UL because it is only 9:1 compression ratio
