Aviation kerosene, also known as QAV, is the fuel that fuels airplanes and helicopters equipped with jet turbines, turboprops or turbo-fans.

Do propeller planes still use leaded fuel?

Jet aircraft and turbine-powered, propeller aircraft do not use avgas, but instead use fuels very similar to kerosene, which does not contain a lead additive.

Why does General Aviation use leaded fuel?

Lead is added to Avgas to help boost fuel octane, prevent knock and engine issues that could result in a loss of compression. Compression loss could cause an engine to stop running, impacting flight safety. Historically, lead was added to a variety of transportation fuels, including motor vehicle gasoline.

How many aircraft use leaded fuel?

Though the use of leaded gasoline in most motor vehicles was banned 25 years ago, leaded aviation fuel is still used in nearly 170,000 piston-engine aircraft across 20,000 airports. EPA estimates that emissions from these airplanes account for about 70% of lead released into the atmosphere.

Can you buy leaded gas in the US?

Actually, you can—leaded fuel is still manufactured for the American market, despite being officially banned by the EPA in the 1990s. Leaded gasoline is technically illegal for on-road use. However, suppliers can sell leaded fuel for race cars, off-road-only vehicles, aircraft, and other specific non-road uses.

Is leaded gas better for engines?

So when it comes to leaded vs unleaded, the rule of thumb is unleaded if you have oxygen sensors and leaded if you don't. In the case of older engines, any leaded fuel with an octane of 110 or close to it works great.

Will leaded gas hurt?

Extremely high lead levels can lead to seizures, coma, and death. Lower levels tend to cause less detectable harm, but there's no safe level of lead exposure: Scientists' current best guess is that any lead exposure at all causes harm. Many of lead's dangers have been known for decades.
