Can General Aviation Transition to Unleaded Avgas by 2030?
As our fuels and oils expert looks back at what was accomplished in 2025 towards general aviation’s transition to unleaded fuel, he questions whether we can meet our self-imposed deadline of 2030 to go completely lead-free.
Navigating General Aviation’s Transition to Unleaded Avgas
General aviation pilots and aircraft owners are asked to read the FAA’s draft Transition Plan to Unleaded Aviation Gasoline and comment on it before March 13, 2026.
The Big Picture on Unleaded Avgas
The EAGLE initiative — Eliminate Aviation Gasoline Lead Emissions — has updated its “Big Picture” flow chart, adding interactive links and pop-up narratives.
UL100E advances in race to unleaded avgas
The American Society for Testing and Materials has published its first specification for UL100E, an unleaded aviation fuel co-developed by LyondellBasell and VP Racing. This milestone brings the fuel one step closer to fleetwide authorization as it continues full-scale evaluation under the FAA’s Piston Aircraft Fuel Initiative (PAFI) program, with testing expected to conclude by late 2026.
Fuel prices fall with the temperature
The average price for 100LL in January 2026 is $6.42. How does that compare to your airport?
Largest all-electric fuel truck unveiled
Skymark Refuelers, in partnership with World Fuel Services and Clay Lacy Aviation, have unveiled the country’s largest all-electric aircraft fuel truck: A 7,000-gallon EV Refueler designed for sustainable fueling operations at airports nationwide.
A warning from the past for unleaded avgas
Oil refineries add 0.5 grams of Tetraethyllead (TEL) per gallon to 80/87 fuel. But why?
New toolkit offers insight into transition to unleaded fuel
The new interactive toolkit, available at flyEAGLE.org, offers regularly updated insights into the U.S. piston fleet, fuel infrastructure, airport fuel availability, 100LL production and logistics, sales volumes, per-capita data, and more.
