I live in corn country and never use ethanol anything. Like has been said before the mileage doesn't work out. 100% ethanol burns 1.5 times the rate of regular unleaded. If you take away all the government money that the ethanol industry recieves it would be a no-brainer at the pump when you saw what you actually are paying for it. I also would never put it in a small motor like that generator as you'd be asking for trouble.
