An Arizona company called Airworthy AutoGas said it plans to start production of a high-purity, low-vapor-pressure 93 octane unleaded aviation gasoline this fall that could replace 100LL avgas in about 80 percent of piston airplanes.
“A growing number of general aviation aircraft do not require 100LL avgas or a 100 octane unleaded drop-in replacement,” noted Mark Ellery, Airworthy’s director of business development. “That, coupled with the scarcity of suitable ethanol-free automotive gasoline in the marketplace, resulted in the development of Airworthy AutoGas.”
