It also has a high vapour pressure, making vapour lock at altitude a
serious risk.



Actually, the vapor pressure with ethanol is lower than gasoline - the
problem is with gasoline /ethanol blends - the vapor pressure of the mixture
tends to peak at about 10% ethanol. The problem then is that if you get a
fair ammount of ethanol in your tank, add some straight gasoline, then the
vapor pressure of the mixture will be higher than either on it's own. A real
problem if you want to build a "flex fuel" control system that will run on
anything from gasoline to E85...
