FAA Approves G100UL as replacement for 100LL AvGas
The FAA signed on September 1 supplemental type certificates that allow General Aviation Modifications Inc.’s 100-octane unleaded fuel (G100UL) to be used in every general aviation spark-ignition engine and every airframe powered by those engines. The move was hailed by the industry as a major step in the transition to an unleaded GA future.
This allows use in all certificated airplanes. Experimental aircraft like Europas can use the fuel without approval. G100UL is compatible with 100LL so existing storage tanks at airports can just add the new fuel with their remaining 100LL fuel. In the US production and distribution is starting and hopefully G100U will be widely available within a year.
