WHY are we using it?
The production of ethanol uses more oil to produce than the same amount of gasoline.
Ethanol is a way to use our own resources vs. importing. But uses more oil during production and more through less power causing lower vehicle mileage.
A very bad deal all way around.
If they go to the E15 blend, more problems than we have now may happen.
