Ethanol Fueling Infrastructure Development

E10 (10% ethanol, 90% gasoline) is available at nearly every fueling station. There are more than 3,500 public stations in 42 states offering E85 (or flex fuel)—a gasoline-ethanol blend containing 51% to 83% ethanol, depending on geography and season. As of 2020, E15 was sold at more than 2,000 stations in 30 states. Some stations offer multiple ethanol blends at one location, often through blender pumps.

To learn about installing infrastructure for blends above E10, see:
