Yes, Alcohol is VERY corrosive and will cause LOT's of problems in
vehicles not designed for it. Sound's like your Gov is a moron, I would
write a nice letter to him and to a few papers about who is going to
provide repairs to vehicles damaged by the fuel.

The E85 vehicles have stainless fuel lines, different injectors and
different programming. Also keep in mind that a vehicle will burn
roughly twice as much alcohol as gasoline. So your mileage with 20% will
be about 2 mpg lower than with straight gasoline.
