ethanol will eat gaskets,hoses and burn valves..thats what they replace ....we use corn for ethanol,only get 50% return for amout of energey used to make it. Sugarcane has a 200% yeild for energy put into it to make ethanol. We are subsidising a losing industry that can only be effective if normal gas is 4$ a gallon. so guess what 4$ is what we pay... sad really
