The EPA, in their push for a green society have OK'ed the use of E15 and have even put out warning labels for display on pumps. The car manufacturers have protested this move and are making the case that cars will be damaged by this fuel and they'll cancel warranties because of this. It will also tank mileage. As with most nonsense, E15 will eventually be mandated by the government, and we'll see lots of damaged cars, mowers and other gas powered equipment. Politicians talk a good game, but in reality they allow crap like this all the time, especially if there's no money in it for them.
