It does not matter what the feed stock is used the BTUs are about the same.

Methanol is 57,000 BTUS/Gal.
Ethanol is about 76,000 BTUs per gallon.
Gasoline is about 115,000 BTUs.

So you can see that both Methanol and Ethanol will give lower fuel mileage 
than gasoline.
To properly burn alcohol the Fuel Air ratio needs to be increased to allow 
more fuel to pass.
