An E15 nozzle is displayed on a pum at service station in Minneapolis, Monday, Oct. 28, 2013 photo. The Environmental Protection Agency cleared the way Friday, April 19, 2024, for E15, a higher blend of ethanol, to be sold nationwide for the third summer in a row. Gasoline with 10% ethanol is already sold nationwide, but the higher blend has been prohibited in the summer because of concerns it could worsen smog during warm weather.
