RFA analysis shows more automakers have approved E15
"An analysis of 2016 model year (MY) warranty statements and owner’s manuals conducted by the Renewable Fuels Association shows that auto manufacturers explicitly approve E15 (15 percent ethanol 85 percent gasoline) use in more than 70 percent of new vehicles. This is up from 2015, when just over 60 percent of MY 2015 automobiles were clearly approved for E15."
