Not to mention that fuels with alcohol have a negative effect on the engine.
Alcohol attracts water and water does not settle out like it does in normal
gasoline. The higher the alcohol content, the more likely it is to get
fuel contamination.

That only applies to current engines though. If someone could build a
high-temp ceramic engine, just to make up an example, water wouldn't
be a problem at all.
