Did I miss any?


Something called "phase separation." At altitude, the gasoline and alcohol
do not remain mixed. To quote the EAA page, "Phase separation is the last
reason, which happens when the fuel is cooled as a result of the aircraft’s
climbing to higher altitude. When the alcohol separates from the gasoline,
it may carry water that has been held in solution and that cannot be
handled by the sediment bowl."

With respect George, I totally agree with your statement but my
question was regarding what damage is caused by the alcohol, not its effect
on performance. I'd like to read the EAA reference, please give me the URL.
