And it makes food costs higher as well.
Ethanol made from beat or cane sugar is excluded from the program so that only corn sugar may be used. What does that tell you about the real reason for the ethanol mandate?
I mentioned that in another comment - but yes. However, going to E-85 blend will not just make food costs high, it will make food costs significantly higher and so everything else follows - just additional way to destroy the US economy.
