Shaping an unleaded future for general aviation

Lead-Free Aviation

Join us in the journey to an unleaded future in general aviation. Learn about the dangers of leaded fuel and how to transition to the safer alternatives.

Our Goal

Assist in the transition to lead-free general aviation

Aircraft Owner Outreach

Informing aircraft owners and flight schools about the benefits of running unleaded fuels in their planes & assisting them in their options.

Industry Collaboration

Collaborating with airports and fuel providers to introduce unleaded options to more airports and phase out leaded fuel.

Regulatory Advocacy

Advocating to local government offices for a transition to unleaded fuel in general aviation to protect public health.

Health Awareness Campaign

Educating the public about the dangers of leaded fuel and its environmental impact.

Public Assistance

Building partnerships and growing support for lead-free aviation through public outreach.

Public Health

According to the U.S. Environmental Protection Agency (EPA), there is no safe level of lead in the human body. In children, the problem is even worse, as even low levels of lead in a child’s blood can harm cognitive function, reduce IQ, and decrease academic performance. The effects can be irreversible and last for their entire life.

Aircraft Lead Emissions

The EPA has found that piston-engine aircraft are the single largest source of lead emissions in the U.S., responsible for 70% of all airborne lead. Emissions from these aircraft cause elevated levels of lead in the air surrounding airports. These emissions have been linked to the adverse health effects listed above.


It has been long enough. The time to change is now.

A Smart Transition

One Step at a Time

The switch to unleaded does not have to be all or nothing. The general aviation fleet is large, and many aircraft are already approved to use currently available unleaded options. Although not every aircraft in the GA fleet can run on lower octane fuel, this does not mean we should stop efforts to start a steady transition to unleaded for those aircraft who can.

No Plane Left Behind

We believe a swift transition is imperative, but many aircraft do still need high octane fuels to run safely and efficiently. Go Unleaded does not support a complete ban on 100LL until viable alternatives reach the market.
