Avgas, also known as aviation gasoline, is a specialized type of fuel designed for use in aircraft piston engines. It has a higher octane rating compared to automotive gasoline and contains low levels of lead for lubrication and anti-knock purposes.
If Avgas is used in a motorcycle engine designed to run on automotive gasoline, it can lead to several problems:
Octane rating: Avgas typically has a much higher octane rating than regular automotive gasoline. Using Avgas in a motorcycle engine not designed for such high octane fuel can cause incomplete combustion, leading to poor engine performance, reduced power output, and potential engine damage.
Lubrication: Avgas contains low levels of lead, which acts as a lubricant and prevents valve seat recession in aircraft engines. However, motorcycles typically have different valve materials and designs that are not compatible with leaded fuels. Using Avgas in a motorcycle engine can lead to accelerated valve wear, decreased compression, and potential engine damage.
Exhaust emissions: Avgas contains lead, which is highly toxic and harmful to the environment. Using Avgas in a motorcycle will result in higher emissions of lead into the atmosphere, contributing to pollution.
It is important to always use the type of fuel recommended by the motorcycle manufacturer. Using the wrong type of fuel, such as Avgas in a motorcycle engine designed for automotive gasoline, can lead to poor performance, potential engine damage, and environmental harm.
