EPA Looks to Move Forward with Blending More Ethanol in Summer Gasoline

The EPA’s newly proposed regulation, a copy of which found on the EPA’s web site, would lift this ban and permit higher concentrations of ethanol in fuel that is sold annually from June 1 through Sept. 1. But for consumers, more ethanol means lower overall fuel economy since ethanol only possesses two-thirds the energy content of a gallon of gasoline. The U.S. Energy Information Administration estimates that a 10 percent ethanol blend into gasoline will decrease a car’s overall fuel economy by three percent; this means that increasing ethanol to a 15 percent blend will bring the average fuel economy down 4.5 percent when compared to just straight gasoline.
