In minimal ratios, ethanol doesn't hurt the engine but when you get to higher ratios of ethanol vs gasoline mix, the ethanol wears out certain components on your engine because it is more corrosive than gasoline ie, the seals and what not.

If you look up E85 and flexfuel vehicles, you'll find that E85 is 85 percent ethanol and 15 percent gasoline. At such ratios it is only recommended in cars which can handle the fuel mainly because of the corrosive tendencies of ethanol on the parts that are affected by it. Flexfuel vehicles means that there was as substitute or beefed up version of a component which would normally be eaten up by the ethanol.
