U.S. Firm Swift Fuels Gains Global Certification for Unleaded Aviation Fuel – Used By More Than 10 FTO’s Globally

10th Sep 2025

USA – Swift Fuels, a U.S.-based producer of unleaded aviation gasoline, has achieved a major industry milestone with the ASTM International approval of a production specification for its 100-octane unleaded Avgas, 100R.

  • The ASTM Production Specification establishes a global benchmark for fuel quality, safety, and performance, enabling broader international acceptance of Swift Fuels’ 100R.

  • The certification follows over 11 years of R&D, involving collaboration with the FAA, engine OEMs including Lycoming, Continental Aerospace, Rotax, Textron Aviation, and Piper, as well as aviation testing laboratories and parts suppliers.

  • The fuel is approved under FAA and EASA Supplemental Type Certificates for use in aircraft such as the Cessna 172S, powered by the Lycoming IO-360-L2A engine.

  • Swift Fuels’ 100R is currently in use at five U.S. flight schools and five European operators across Austria, Belgium, Germany, and the Netherlands.

  • The company’s European distributor, Bollinger Aviation, has commenced deliveries to Ganderkesse Airport in Germany, where resident AAG Flight Academy became the first European flight school to operate the fuel in training and charter activities.

  • 100R is dyed green to distinguish it from traditional 100LL and is priced comparably.

Statements

  • “The passion for flying and the desire for innovative solutions are part of our company’s DNA. This is especially true for investments in environmentally friendly and sustainable aviation,” said Ralf Sauer, Managing Director of AAG Flight Academy. “When Bollinger Aviation offered us the opportunity to become the first European user of unleaded AVGAS in training and charter operations, we immediately responded with a ‘yes’ – after all, our AAG Flight Academy has a C172S with a suitable engine.”
