I hate the whole idea of ethanol. So much wildlife habitat has been destroyed to grow corn for ethanol. I don't remember the exact figures, but Ducks Unlimited magazine had several articles on this subject. And as fuel ethanol is not very efficient, mileage wise. One may spend less money per gallon buying "ethanolized " gasoline, but then the mileage will be less. Furthermore, it takes more fossil fuels to grow corn and make ethanol than ethanol can replace. It's like exchanging a dollar bill for 90 cents in small change. And, as you wrote, ethanol is harmful to small engines. I do not even buy ethanol/gasoline mixture for my Ford F 150 even though it is supposed to run on it. It's a matter of principle more that anything else. My other vehicle (my wife's) is a 2008 Ford Escape bought in Alaska (where no gas station carries ethanolized gas), and simply will not run well on ethanol. Once my wife filled it up with that crap, and when I drove it I thought something was wrong with the engine or the transmission. It could not accelerate beyond a certain rpm, and was cutting out.It also eats rubber and plastic seals, o-rings, and gaskets
