In Washington, more than 80 percent of new 2017 model year (MY) vehicles are explicitly approved by the manufacturer to use 15 percent ethanol blends (E15), according to an analysis of warranty statements and owner’s manuals conducted by the Renewable Fuels Association (RFA). That is up from last year, when approximately 70 percent of MY2016 vehicles were approved by automakers for the use of E15.
For the first time, Hyundai Motor Company has approved the use of E15 in MY 2017 Hyundai and Kia vehicles, joining the majority of its auto competitors. Together, Hyundai and Kia represent slightly more than 8 percent of the U.S. light-duty automobile market.
In 2012, EPA approved the use of E15 in vehicles built in MY 2001 or later. However, auto manufacturers did not retroactively endorse the use of E15 in legacy vehicles that were already on the road.
