Myth or fact Hi folks, the Rotax won't indeed mind a little bit alcohol in the fuel. However, there are two other issues: - the fuel system itself, especially seals, pumps, etc. - fuel with ethanol and / or methanol is much more volatile and thus more prone to vapor lock.

Myth or fact From: "Roger Lee" Hi Thilo, Eric Tucker, of Kodiak/Rotax, stated that there is nothing in a Rotax for the alcohol to be an issue. No seals or parts that should get damaged. Other engines yes, but not a Rotax because of the way it is Mfg. It will only cost you some BTU's on the power side. He recommended that we use either a blend of 100LL with 91 oct. or 100LL above 8k' as a precaution to vapor lock. -------- Roger Lee Tucson, Az.
