Marathon Petroleum Corp., the largest U.S. oil refiner following its $23.3 billion acquisition of rival Andeavor this month, is weighing a plan to start sales of high-ethanol gasoline at its stations in Minnesota, according to people familiar with the matter.

The Findlay, Ohio-based company may sell so-called E15 gasoline, a blend that contains as much as 15 percent ethanol, at stations in the state, said the people, who asked not to be identified because the information hasn’t been made public. Offering the higher blend would help Marathon compete with others selling it and also curry favor with political leaders in Minnesota, the fourth-biggest U.S. producer of corn-derived ethanol, the people said.
