Although the federal government has approved year-round sales of E15, don’t expect to see it at every pump anytime soon. “You just can’t get that infrastructure changed quickly. It’s unlikely many gas stations will change from E10 to E15,” said Wally Tyner, agricultural economics, Purdue University. Industry cost estimates for new pump and storage tank installation would likely prohibit the fuel to be taken up by smaller companies. Rural areas may experience more pressure to install because farmers want to support each other, Tyner said. (Columbus Dispatch)
