ethanol does a nice job on paints, glue (that holds filter media together) and various other essential materials found in and around a car. One area that I am not sure the powers that be have thought about to any real extent is the effect of the blend on the oil film on the rings. Ethanol brings a whole host of interesting chemicals reactions to a long list of dynamics at play.

Don't even mention FAME (fatty acid methyl esters) aka biodiesel. Great parts washer solvent...does a great job at breaking down petro-chemicals and isn't a fan of epoxy resins which bind fiberglass...
