Can anybody report back how the aviation fuel lube works?

Unfortunately, ethanol-free gas is not available for many people... I would be one of them. ...
Any General Aviation airport, ask for 100LL (low lead). Bring your own metal jerry cans (don't ask). If they ask, tell 'em it's for a '49 tractor, as it has lead in it (duh).
With luck, they may also sell MOGAS. Which is automotive 'pump' gas, ~93 octane, lead and ETOH free.
In both cases, it can be expensive, the 100LL more so.
On another front, a company, let's call them "Swift Fuels", is testing a lead free substitute for 100LL. If not aware, most every piston airplane engine requires 100LL (or better), and it's NOT necessarilly because of the lead content. Vapor pressure, stable in storage, atomization, cold weather performance, compatibility with rubber bits and pieces, and a raft of other things. It's scarse as hen's teeth right now though.
