“[B]ecause ethanol packs less energy per gallon than gasoline does, vehicle owners can expect to get even lower fuel mileage from the expansion of E15 fuel (a blend of 15% ethanol with 85% gasoline) under the new mandate to include more ethanol in automotive fuels, which would be 4% to 5% less than they would achieve if they only filled their vehicles with 100% gasoline. Today’s vehicle owners already pay a fuel efficiency penalty of 3% to 4% lower gas mileage from the E10 ethanol-gasoline fuel blend[.]”
