General Aviation Modifications, Inc., (GAMI) has announced the STC for its G100UL avgas for Lycoming O-320, O-360, and IO-360 engines. The move came with broad support and cheering from those in the industry who have been working hard towards solving the problem of leaded fuels in piston-powered aircraft.
The STC comes after years spent by GAMI in the research and development of an unleaded avgas solution. This initial result is the proprietary, high-octane G100UL fuel, optimized for the series of normally aspirated, 4-cylinder engines that power a significant portion of the light GA fleet. It’s a step towards the big goal of a replacement fuel for 100LL that will incur no loss in safety and performance for those aircraft and can be delivered reasonably within the GA community.
