Swift’s Unleaded 100R fuel does not meet or match the ASTM Standard for 100LL or their own UL94… They have done all of the necessary testing and submitted results for a new ASTM spec that will cover and define their formulation of 100R unleaded fuel. Swift has a refinery, and distribution setup for a number of airports, including rail transport logistics and transloader in LA area and San Francisco Bay Area to ship rail cars and then deliver truckloads to tanks at (currently) 6 Bay Area Airports. The number of fuels any airport can handle is a function of how many tanks they have, which are hideously expensive to add today. Swift plans to transition for UL94 to 100R as soon as the ASTM spec and FAA STC are signed off, for their existing customers. They will add customers as fast as they can from there, while discussing licensing to major Avgas refiners (like Chevron in western US) to begin brewing 100R and distributing in much larger quantities.
