Swift Fuels is the only company selling unleaded avgas in the United States and has expanded its distribution network across the country.
Swift sells UL94—which is basically the current avgas formulation without tetraethyl lead—and about two-thirds of the U.S. piston-engine fleet is capable of safely using that fuel today.
Swift is available at airports from California to Maryland and Michigan to Florida.
The company also makes a higher-octane fuel that the FAA selected as one of two finalists in the agency's ongoing Piston Aviation Fuels Initiative process.
