Swift Fuels Launches UNLEADED 94 MON Avgas

Swift Fuels, LLC, a recognized leader in developing unleaded aviation fuels, will introduce its Unleaded 94 MON Avgas at the annual AirVenture Oshkosh Air Show, July 20 – 26, 2015 being held at the Wittman Regional Airport in Oshkosh, Wisconsin. The company will provide live open sessions 8:30am – 5pm in Booth # 461 throughout the week, and a public forum to showcase the benefits of unleaded on Friday morning, July 24th at 8:30am on Forum stage 6.

Groundbreaking Unleaded Fuel – Availability in Key U.S. and Canadian Locations

Swift Fuels, working with key avgas producers and distributors, is now making plans to supply unleaded 94 MON avgas to select regions in the United States and Canada. This premium quality unleaded fuel, tailored for lower-octane piston-engines, is already certified and meets ASTM standards for aviation gasoline. The fuel will not replace 100LL now sold at airports for high performance aircraft. Moreover, Swift Fuels’ high octane fuels remain actively part of the PAFI program seeking to replace 100LL on a “fleet-wide” basis. Swift Fuels believes the introduction of a cost-effective unleaded fuel in selected markets helps to begin the ultimate transition. As part of its unleaded fuel transition strategy for 94 MON avgas, the company has forged an exclusive partnership with Petersen Aviation to offer new Avgas Supplemental Type Certificates (STCs) for thousands of aircraft that are now compatible with 94 MON avgas. Swift Fuels and Petersen Aviation have worked with the FAA for approval of the required STCs, which could allow most any class of rated 94 motor-octane-number (MON) or lower to use Swift’s fuel. Swift’s team estimates that more than 40% of the existing US aircraft fleet is already qualified with FAA ’s to fly using its 94 MON aviation gasoline and more are planned soon.

Many piston-engine aircraft with engines that require avgas having a minimum octane rating at or below 94 MON are now eligible to buy the appropriate STC certificates in order to fly the fuel, including:

  • Cessna:  Skyhawk (172 R&S), Cutlass (172 RG’s), Cardinal (177’s) and Skylane (182’s)
  • Piper:  Seminole, Comanche and Aztec
  • Beechcraft:  Musketeer, Travel Air and Duchess
  • Maule:  all Lycoming-powered models
  • Mooney:  models A-D and G
  • And many other aircraft models with engines that require avgas rated at or below 94 MON

Aircraft with autogas STC’s are already eligible to use the premium 94 MON avgas “as-is”. In addition, Light Sport aircraft powered by Rotax engines are typically already manufacturer-approved to use 94 MON avgas “as-is”. Pilots can check with Swift Fuels to verify their unique aircraft requirements. The Swift Fuels team, along with Todd Petersen, will provide information at Oshkosh about the benefits of its fuel, the avgas STC’s, the process of getting airplanes ready for (e.g. placards, inspections, training, etc.), airport tankage considerations and initial plans for fuel distribution.
