Join AOPA, GAMI, Avfuel for unleaded fuel webinar

GAMI announced supplemental type certificate approval for its high-octane unleaded avgas on July 27 during EAA AirVenture in Oshkosh, Wisconsin. The STC allows the fuel to be used in a limited number of Cessna models with Lycoming engines. GAMI expects the FAA to expand its approved model list.

GAMI has tested the amber-colored fuel for nearly a decade and says that it will serve as a drop-in replacement for 100LL in most piston aircraft engines and can be mixed with 100LL. At 6.2 pounds per gallon, it weighs slightly more than 100LL. GAMI has also tested the fuel successfully in turbocharged and normally aspirated Continental IO-550s and Lycoming IO-390s and IO-540s without detonation occurring. These high-compression engines are particularly susceptible to detonation in some conditions.

GAMI has teamed with Avfuel to develop a distribution plan for the fuel.

“Avfuel is establishing a supply chain to responsibly bring G100UL avgas to market on a commercial scale,” Avfuel announced in a press release July 27. “Together, GAMI and Avfuel have committed to a process that will ensure G100UL avgas is available to all legitimate distributors and vendors on an equitable basis in terms of access and economics.”

During the webinar, the three industry leaders will discuss how FBOs and airport managers can explore ways to get ready to use this fuel once it is more broadly approved.
