Simple arithmetic demonstrates the stupidity of EtOH/octane fuel: a 10% mix reduces mileage coincidently by 10%, therefore a 20 mile trip in a 20mpg auto would use 1 gal of straight octane or 1.1 gal of mixed fuel. That 1.1 gal contains 0.99 gal of octane, ie- you "save" only 1% of the petroleum fuel. Now they tell us we have about 100 yrs worth of petroleum left, so if the whole world were to use 10% mix (requiring the use of half the world's yearly maize production) , we would only make that oil last 101 yrs..

Is it a good idea to turn food or other bio source into EtOH for fuel?
