I drained and then filled my boat before winter storage with gas I bought at a marina. They assured me that it was ethanol-free, and they would be able to get ethanol-free gas until Jan 1, when a new law goes into effect, apparently, although they weren't too sure about the details.
I am going to go back to a marina in the next couple of days to fill my big gas cans for my generator and for storing my motorcycles. In a pinch, the Sta-Bil folks seem pretty confident their new product is ethanol compatible.
