PICKERINGTON, Ohio — The U.S. Environmental Protection Agency will require all consumers to buy at least four gallons of gasoline from certain gas pumps after the new E15 ethanol-gasoline blend is introduced into the market, the American Motorcyclist Association reports.

The EPA revealed the requirement to the AMA in a letter dated Aug. 1, responding to AMA concerns that E15 — a gasoline formulation that contains up to 15 percent ethanol by volume — could be put in motorcycle and ATV gas tanks inadvertently when consumers use blender pumps. A blender pump dispenses different fuel blends through the same hose, and the vast majority of motorcycles and all-terrain vehicles in use today aren’t designed to operate on E15 fuel.
