WEST DES MOINES, IA – The Iowa Department of Revenue released the 2025 Retailers Motor Fuel Gallons Annual Report, showing E15 sales increased 60% in only one year to over 410 million gallons sold. At the end of 2025, almost half of Iowa fuel stations offered E15, with the blend accounting for 27% of gasoline sales, according to press release issued by IRFA.
“The massive growth in E15 sales reflects the success of Governor Reynolds’s E15 Access Standard,” said Iowa Renewable Fuels Association (IRFA) Executive Director Monte Shaw. “With Iowa drivers saving an average of 15 cents per gallon by choosing E15, the cost savings equal an estimated $61.5 million. E15 is well on its way to becoming the new normal fuel in Iowa.”
The report also showed that almost 51 million gallons of biodiesel were sold in various blends during 2025. This is down from about 82 million gallons of biodiesel sold in all blends during 2024.
“2025 was the predictable result of being completely unsettled by federal policy,” commented Shaw. “Low RFS blend levels for 2025, combined with no guidance on federal tax credits during the same period, disrupted the biodiesel market. Iowa biodiesel took a big hit but can weather the storm and rebound quickly with the right policies put in place.”
The Iowa Department of Revenue identified retailers for the report using information from the Iowa Department of Agriculture and Land Stewardship’s motor fuel license database and from internal records. The full 2025 report can be found here.
