OMG, they are just determined to destroy as many engines as possible, aren't they? Ethanol has been such an utter failure it is unreal. And yes, I had a motorcycle engine pretty much destroyed due to ethanol. And my current one has constant issues with the gas cap corroding due to ethanol. It attracts water, it gives LOWER miles per gallon, it costs more, it eats up the fuel system in many vehicles, it currently pushes up food prices, actually doesn't reduce dependence on fossil fuels (fertilizer and processing), and on top of it all, it doesn't reduce emissions AT ALL. It has to be one of the worst blunders ever.
FAIL FAIL FAIL
Take the wasted resources from ethanol and please invest that money in battery technology so we can get closer to viable electric vehicles.
