Ethanol is just another farm subsidy to ADM. The oil companies can meet the
emissions requirements without ethanol, and ethanol lowers the milage. What
do you think ethanol costs per gallon?

People who have studied ethanol have determined that if you add in all
of the secondary effects, it costs more energy to produce ethanol than
it delivers as a fuel. The ethanol lobby is very strong in farm states
however for obvious reasons.
