The only one down here that I have seen with that corn garbage in it is Racetrac.
I have noticed sometimes after pumping at Racetrac too much the car does seem to be missing a small umph to it. Ethanol sucks! The car runs like crap on it and it costs more to make then gas. Look how much the damn price of rice, corn and wheat have gone up recently. For this garbage we might as well be pi$sing in our gastanks!
