the oil companies could care less about ethanol. they know it is a horrible idea otherwise they would have started making it years ago. but it uses to much corn which raises the price causing ethanol to be profitless. ethanol has been around for a long time but is not a good fuel source for automobiles. this ethanol thing is going to be short lived. and ethanol plants are actuall losing money right now cause of the high corn prices and the low fuel prices so i guess we'll see what happens in a couple years.
