E15 explicitly approved by most auto manufacturers for 2023 models

In Washington, the Renewable Fuels Association’s annual review of vehicle owner’s manuals and warranty statements indicates that E15 is explicitly approved by the manufacturer for use in the vast majority of model year 2023 cars and light trucks. Notably, for the first time, Mitsubishi lists E15 as an approved fuel in some of its 2023 vehicles. The U.S. Environmental Protection Agency has approved the use of E15 in all vehicles built in 2001 or later, representing more than 96 percent of the vehicles on the road today, but automakers only began listing E15 as a recommended fuel in 2012.

According to the RFA analysis of model year 2023 vehicle owner’s manuals and warranty statements and current market share data, more than 94 percent of new light-duty gasoline vehicles are explicitly approved by the manufacturer to use E15. Only Mercedes-Benz, Mazda, and Volvo do not list E15 as a recommended fuel in their owner’s manuals, even though E15 is legally approved by EPA for use in all vehicles built since 2001. Mitsubishi lists E15 as an approved fuel for the 2023 Outlander, but the fuel does not appear in owner’s manuals for other models.

Notably, BMW and Mini continue to approve the use of gasoline containing up to 25 percent ethanol in their vehicles. New for 2023, Toyota’s GR Supra—co-developed with BMW—also follows suit by allowing E25.
