The Iowa Renewable Fuels Association is projecting that E15 will top E10 to be the number one fuel in Iowa by the end of this year.

“It will be close, but E15 is on track to become Iowa’s top-selling fuel for 2026,” said Iowa Renewable Fuels Association Executive Director Monte Shaw. “With 46 million gallons in August, Iowa drivers are sending a clear message: they want E15. As more Iowa retailers have given drivers the chance to buy E15, the numbers are impossible to ignore.”

According to the latest monthly fuel tax data released by the Iowa Department of Revenue, Iowa fuel terminals distributed more than 46 million gallons of E15 during August, the second highest amount on record and total E15 sales in the state for August were just behind the record 48 million gallons sold in May, continuing a strong year of growth for the ethanol blend.
