"Ethanol is costing us our history by destroying vintage cars and machines."

Local airport J Earl might be your answer. 100LL and "Mechanic in a Bottle" works for me in the lawnmower.

Hold tight, a 91 octane and a higher octane non-leaded Gen Av fuel is being rolled out ( Swift Fuels ), but availability is spotty at the moment.

Ethanol is STILL corrosive. Adding octane doesn’t change that.

You do make a good point. I should just start buying gas at the airport.

I bought gas at a station in Durango, CO a few weeks ago. They were selling ethanol free right there at the pump for about $.30 more/gallon. I've never seen this anywhere else (I live about 1400 miles from Durango).
