I don't think that's quite true. Gas needs octane boosters to work well in modern engines. Lots of things have been used for that, such as tetraethyl lead and MBTE. Those have been shown to have rather nasty environmental effects, so the EPA says don't use them. Ethanol works, is relatively cheap, and environmentally benign, so that gets used.

But E85 is a different thing than the 10% or so ethanol used as octane booster/oxygenator in normal gasoline.
