I will not argue the shelf life or the damage it does to hoses in time. I ve always said if the government is going to make us use it, it should at least have alot more octane like 100.
But....when corn is used to make ethanol the chief byproduct is Millersgrain. It's a very hi energy livestock feed. Cattle love the stuff, it's like feeding a kid candy, they can't get enough of it.
