Iowa E15 Sales Smash Records in September 2026

Iowa set a new record in September 2026 for E15 fuel sales, with over 47 million gallons distributed across the state. This surpassed the previous monthly high of about 47 million gallons set in May and exceeded the 46 million gallons sold in August, according to data from the Iowa Department of Revenue and the Iowa Renewable Fuels Association (IRFA). The trend suggests that E15 could soon become Iowa’s top-selling fuel for the year, potentially surpassing E10.

E15, which contains 15 percent ethanol compared to E10’s 10 percent, is gaining popularity among Iowa drivers. Monte Shaw, IRFA Executive Director, noted that the high sales figures demonstrate consumer preference when E15 is readily available. He stated, “September was another record month for E15, and Iowa drivers are making their preference clear. More than 47 million gallons in one month shows what happens when drivers have access to E15. They choose it.”

The fuel’s affordability is a key factor in its growing demand, as E15 typically sells for 10 to 40 cents less per gallon than E10. Additionally, E15 supports Iowa’s agricultural sector by boosting demand for corn and domestic ethanol production. Retail prices vary by location and market conditions.

Industry advocates, including the IRFA, are pushing for federal regulations to allow year-round E15 sales nationwide, replacing the temporary summer waivers that have been in place since 2022. This move could further solidify E15’s position as a preferred fuel option.
