Ethanol Fueling Infrastructure Development

E10 (10% ethanol, 90% gasoline) is available at nearly every fueling station. The number of stations offering E85 (or flex fuel)—a gasoline-ethanol blend containing 51% to 83% ethanol, depending on geography and season—is smaller but continues to grow. As of 2019, E15, a relatively new ethanol blend, was sold at more than 1,700 stations in 30 states. Some stations chose to offer multiple ethanol blends at one location, often through blender pumps.

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