    While not exactly on topic, it just occurred to me. Since in the US there is the mandated ethanol inclusion in all automobile gasoline, what is the impact, if any, on use of the blended gasoline in engines like Rotax? Y understand that 100LL is not the optimal fuel for it.

      Rotax will handle auto gas with or w/o ethanol…There are usually a few ethanol-free stations in towns.

      I do not know the current requirements for the 912. In the early Rotax publications they stated to not use over 5% ethanol blend gasoline. The use of 100ll avgas was approved but with the requirement that synthetic oil NOT be used and the oil must be changed more often. This was/is a problem with keeping the lead suspended so as to prevent stuck rings,valves and fouled spark plugs. The cry for a 100oct. replacement fuel is bad for many of us, I now fly a continental A65, the engine was designed and certified with 73oct. UNLEADED avgas. The 80/87-grade 80 avgas had only a max allowable amount NOT a minimum so much of it was no-lead as well. Marathon does market a 91oct. “recreational” gasoline that is ethanol free, it is sold primarily for marine use.
