Growth Energy announced that summer sales of E15—a fuel with 15% renewable ethanol often sold as Unleaded 88 at the pump—are up 46% in 2019 compared to 2018 on a per-store basis.

Additionally, for the first time, this past summer saw the number of stores offering Unleaded 88 increase. Led by Casey’s, the retail industry added 149 stores over the summer months. The 2019 summer driving season was the first summer Unleaded 88 was sold without restriction and this increase underscored the fuel’s popularity with drivers who have logged more than 11 billion miles on it.

Growth Energy works with leading retailers including Casey’s, Cumberland Farms, Family Express, Holiday, Kum & Go, Kwik Trip, Minnoco, Murphy USA, Protec Fuel, Pump & Pantry, QuikTrip, RaceTrac, Royal Farms, Rutters, Sheetz, and Thorntons to give more drivers access to Unleaded 88 at more than 2,000 stations across the U.S. These retailers sell between 2.2 to 2.5 million fuel gallons per year which amounts to more than 200 percent more fuel gallons per year than what the average fuel retailer sells annually.
