Family-owned Kwik Trip has expanded its offering of fuel containing 15 percent ethanol to 330 of its nearly 600 locations in Wisconsin, Minnesota and Iowa.

Kwik Trip started offering E15 in just four stations in February 2017 and labels and markets it as “unleaded 88.”

The AMA remains concerned about the rapid spread of E15 and higher ethanol blends, because none of the estimated 22 million motorcycles and ATVs in use in the United States is certified by the U.S. Environmental Protection Agency to operate on blends with more than 10 percent ethanol by volume. And some vintage bikes require E0 (no ethanol) to run properly.

Increased availability of E15 may result in less availability of E10 and E0.

Motorcyclists and ATV owners are urged to be alert when fueling their vehicles to ensure use of the fuel recommended by the vehicle manufacturer. Don’t just shop price.
