With Competition in the Unleaded Avgas Scene, Will STC Pricing Come into Play?
The FAA’s EAGLE initiative has seen another buyer in South California’s Golden West Jet Center, who will begin offering unleaded avgas in the form of Swift’s UL94.

The Oxnard Airport FBO received its first tanker of UL94 gas in March, providing locals a way to avoid the use of leaded fuel in their piston-engined aircraft. The Swift product stands apart from some competing lead-free avfuel options by offering a more consistent buy-in for the STC, standing at $100 right now. The other big name on the leadless avgas block, GAMI’s G100UL, charges on a sliding scale for its STC, instead basing its pricing on engine size and output. Golden West will now offer Swift’s UL94 as a part off a network of providers expanding throughout the west coast.
“Golden West Jet Center joins a network of aviation businesses across the country dedicated to leadership in providing an unleaded aviation gasoline alternative and demonstrating progress toward the EAGLE initiative goal,” said NATA CEO Curt Castagna.
“It took several months to work through the logistics on how we were going to store the fuel,” said Priscilla Howden, General Manager of Golden West Jet Center. “In the end, Avfuel was able to send us a second fuel truck and we received the UL94 by a truck-to-truck transfer. Oxnard Airport Ops was on site to ensure a smooth process.”
They have clarified that the UL94 remains clearly segregated from its 100LL supplies, preventing misfueling mixups. Helping out in that avenue, Howden plugged the NATA misfueling prevention site as an excellent source of safety information for airport operators. “As part of the education process, Swift has a great website that provides news and details on UL94,” she added.
“We know not everyone can take this fuel yet, but we felt it was important to provide UL94 fuel to pilots who want it,” Howden added. “As part of the education process, Swift has a great website that provides news and details on UL94.”
