Nope.  I believe ethanol burns cooler.  It does, however, have a lower
BTU content than gasoline and is less volatile and therefore produces
less power per given volume.  Hmmm, this brings up a good point and a
challenge to my argument.  If a fuel is less volatile, does the engine
have to run hotter to burn it?  I've been out of the business too long
to remember the correct answer to this.
