Down here several Marinas and convenience stores on the water stock an ethanol free mid-grade gasoline, usually 89-90 octane.
I use it in my boat motors, my R3R, and all my small engine stuff.
There's a Whetstone Oil Company with retail outlets in Brooksville and Crystal River that carry it, and the convenience store in Hernando Beach (four miles from my house in WW) carries a "Rec-90;" 90 octane ethanol free.
I put the PRIG stabilizer into all my gas cans, so that anything that receives the gas will be able to sit a while if necessary, and still run with no problems.
