Biden is temporarily allowing E15 NOT E85. “To be clear, E15 is gasoline. It's 88-octane fuel that is refined with 85 percent unleaded gas and 15 percent ethanol. E15 has been available through retail distributors since 2012 and, like the more popular E85 (unleaded gas plus between 51 and 83 percent ethanol), it can be used in all flexible-fuel vehicles.” Sep 21, 2021 MOTOTREND
