✈️ The transition to unleaded avgas is moving from theoretical to operational. The Federal Aviation Administration has released its draft Transition Plan to Unleaded Aviation Gasoline for public comment, marking a major step toward the goal of a lead-free general aviation fleet by 2030.
Whether you are a pilot, aircraft owner, or mechanic, this plan affects you. Key takeaways from the report include:
A Four-Phase Rollout: The transition begins now, with a target for most of the U.S. to be lead-free by the end of 2030 (with Alaska following in 2032).
The Contenders: Learn about the three primary high-octane fuels—GAMI G100UL, Swift Fuels 100R, and LyondellBasell/VP Racing UL100E—and how they differ.
Crucial Safety Alert: While these fuels can be mixed with 100LL, they are not yet cleared to be mixed with each other.
Maintenance Considerations: Early data suggests some unleaded fuels may impact specific sealants or act as stronger solvents, potentially loosening old deposits in your fuel system.
The FAA is seeking your input! You have until March 13, 2026, to review the plan and submit your comments.
