As the first DeLand Sport Aviation Showcase takes off at DeLand Municipal Airport in Florida, Swift Fuels reports its is selling its unleaded UL94 avgas with full service refueling onsite for $3.95 a gallon.
Officials with the company are also on track to present two forums during the Nov. 3-5 show.
Swift Fuels’ unleaded 94 MON avgas (UL94), the only unleaded aviation gasoline commercially produced in the US, is now available nationwide. UL94 is an “all-hydrocarbon” premium gasoline, designed specifically for aircraft use, which is 100% lead-free and contains no ethanol.
It is approved for lower-octane demanding aircraft and engines, which represent up to 65% of the U.S. piston fleet.
The unleaded avgas requires no hardware modifications to the aircraft. According to company officials, it is “drop-in ready” for the following types of aircraft:
- All light-sport aircraft (LSA) powered by Rotax engines approved for autogas are already manufacturer-approved to use unleaded 94 MON avgas “as-is.”
- Aircraft placarded with autogas supplemental type certificates (Autogas STC’s) are also FAA-approved to use the 94 MON avgas “as-is.”
- Aircraft/engine combinations that are TCDS (type certificated) for 80/87 octane avgas (or lower octane) are also approved to use UL94 “as is”.
Aircraft engines that demand min 91-MON or 94-MON avgas may have airframes that require an avgas STC to use UL94; pilots can verify if their aircraft make and model are approved by visiting Swiftfuels.com/STC. Once placarded with an avgas STC, UL94 is good to go, company officials note.
Aircraft engines that require min 100-MON avgas may not use UL94.
