The list of vehicles approved to run on 15 percent ethanol blends is growing.

Nearly 90 percent of new 2018 model year (MY) vehicles are explicitly approved by the manufacturer to use 15 percent ethanol blends (E15), according to the results of an annual analysis of warranty statements and owner’s manuals conducted by the Renewable Fuels Association (RFA).That’s an increase of nine points from last year’s analysis.                       

For the first time, Nissan Motor Company has warrantied the use of E15 in most of its MY 2018 vehicles, joining the majority of its competitors.

The Detroit Three (Chrysler, General Motors and Ford), which collectively represent 44 percent of U.S. market share, all continue to clearly allow E15 in their vehicles. GM started approving the use of E15 with its MY 2012 vehicles, while Ford joined the following year and Chrysler began E15 approval with its MY 2016 vehicles.

"Automaker acceptance and approval of E15 continues to expand rapidly, and almost all new 2018 vehicles carry the manufacturers’ explicit allowance to use this lower-cost, cleaner-burning, higher octane fuel," said RFA President and CEO Bob Dinneen in a release. “This analysis should put to rest any myths still being propagated by the American Petroleum Institute and its cronies that automakers don’t allow or warranty the use E15.”
