Since ethanol has been a part of fuel for many decades, the vast majority of auto parts today are fine with ethanol. There are exceptions, like the Ducati gas tanks, but by and large ethanol is not a problem in any fuel-injected vehicle.
Triumph has had the same problem with their plastic tanks and have somehow managed to avoid a recall like Ducati did. It doesn't help that European vehicles aren't designed to account for an alien fuel.
As the owner of 3 ducatis, a snow blower, and a generator... when ethanol gas sits around for a while it does awful awful things:( Fuel stabilizers help a little, but the only way to REALLY make things work is to either run the engines at LEAST once a week all year, or to fully drain everything, and then deal with another sort of hassle when you need the generator running immediately..
While my car runs the ethenolized gas okay, it kills me knowing that I'm losing HP/efficiency just due to corn subsidies:(
Using ethanol as an oxidizer instead of MTBE looks like pretty much a no brainer. I guess the blend is being maxed out instead of just using the appropriate amount needed for emissions control, but the use of ethanol doesn't just come down to subsidies.
