Why Would People Want E15?
Ethanol is about one dollar a gallon cheaper than gasoline. If the entire savings were passed along at the point of sale, diluting gasoline with 15% ethanol would make the resulting blend about five cents per gallon cheaper than the E10 blend of regular gas. With its 15 percent ethanol content, studies show that E15 fuel will reduce gas mileage by only a bit, not enough to erase the benefit of ethanol’s cheaper price. E15 fuel has only recently been certified for sale in this country.
