Discover the benefits of providing unleaded fuel at your airport/FBO. Find out what option is best for you.
UL94 – An unleaded aviation fuel designed for lower-performance, lower-compression engines that don’t require the high-octane protection of traditional 100LL avgas. Produced by Swift Fuels, UL94 offers a lead-free alternative that meets ASTM standards for compatible aircraft. Many piston engines are certified to operate on UL94, making it an appealing option for airports or FBOs serving such planes. However, because it lacks the octane necessary for high-performance engines, UL94 is not a universal replacement for 100LL, and will most likely not fit the needs of all the aircraft at your airport.

G100UL – Developed by General Aviation Modifications Inc. (GAMI), G100UL is a 100-octane unleaded fuel designed to be a drop-in replacement for 100LL avgas. It is approved for all spark-ignition piston engines, making it a great option for FBOs seeking a single unleaded fuel solution. This flexibility helps simplify fuel management and ensures that both high and low-performance aircraft can operate on the same fuel, making it more financially reasonable.

Currently, there are a few different manufactuers undergoing development of other unleaded fuel options through the STC and PAFI/EAGLE pathways but they are not yet widely available/approved.
