Ethanol accounted for 11.06 percent of the nation’s gasoline in October 2025, marking the first time in history that the monthly blend rate has topped 11 percent. That’s according to a release from the U.S. Energy Information Administration. The Renewable Fuels Association said the record-high blend rate reflects the expanding use of E15 and flex fuels like E85, and should put to rest the myth that the so-called “blend wall” prevents ethanol from making up more than ten percent of the gasoline pool. “The new data provides clear evidence that ethanol is continuing to gain market share in the U.S. fuel market as drivers increasingly choose lower-cost, cleaner-burning E15 and flex fuels like E85,” said RFA President and CEO Geoff Cooper. “The numbers also prove that the fictitious ‘blend wall’ is nothing but an imaginary barrier created by those who oppose American-made renewable fuels produced from American-grown crops.”
