(Undated) U.S. sales of E15 (15% ethanol gasoline) reached a record 1.52 billion gallons in 2025, up 23% from 2024. Growth was driven by more stations offering E15 and higher sales per station. Iowa saw a 60% jump (over 410 million gallons) due partly to a state mandate requiring availability, while Minnesota sold an estimated 169 million gallons. Together, the two states totaled 579 million gallons, though they are the only ones with reliable data.
Nationwide, about 4,600 stations offered E15 by the end of 2025. Sales estimates are based on average station volumes from Iowa and Minnesota.
Key reasons for growth include:
- Expanded access, supported by federal infrastructure funding.
- Lower prices compared to regular gasoline (often at least 25¢ cheaper).
- Summer sales waivers allow E15 use despite regulatory limits.
However, uncertainty around these temporary waivers has slowed wider adoption. Permanent approval for year-round E15 sales is widely seen as the main barrier to further growth.
E15 also helps stabilize fuel prices by increasing supply and offering a cheaper alternative to gasoline, especially during global disruptions. Expanded use could benefit consumers, farmers, and the broader economy, with studies suggesting major economic gains if fully adopted.
