That doesn't sound likely. Otherwise the popular method of alcohol
testing wouldn't work. You can test test the presence of alcohol in
gasoline by mixing gasoline with some water in a test tube, agitate the
tube, and check to see if the water level rises.

On the other hand, if you have an engine that can burn alcohol, perhaps some
amount of water in the alcohol could boost the performance of the engine ala
water injection in old military aircraft. You could turn some of that
wasted heat into steam before dumping it out the exhaust.

I never quite understood why injecting water into engine will increase
its performance. I have no doubt it's true that Boeing used to do that
on their jet engines. Anyone here can provide a scientific answer?
