While Avgas (aviation gasoline) may seem like a viable option for motorcycles due to its high octane rating, it is generally not recommended to run Avgas in a motorcycle engine. Here's why:
Lead Content: Most Avgas formulations contain lead, which is used as an octane enhancer and to provide lubrication for certain aviation engines. Lead is harmful to the environment and can cause damage to the emission control systems, catalytic converters, and oxygen sensors found in motorcycles. Using Avgas with lead in a motorcycle can result in increased emissions and potential damage to the engine components.
Fuel System Compatibility: Avgas has different chemical properties compared to automotive gasoline or motorcycle-specific fuels. It may not be compatible with the fuel system components of a motorcycle, such as fuel lines, seals, gaskets, and carburetors. The use of Avgas can cause deterioration, swelling, or leaks in these components, leading to fuel system malfunctions.
Availability and Cost: Avgas is primarily designed for aviation use and may not be readily available at standard gas stations or motorcycle fueling stations. It is also typically more expensive than regular automotive gasoline or motorcycle-specific fuels. This limited availability and higher cost can make it inconvenient and uneconomical to use Avgas in a motorcycle.
To ensure optimal performance and longevity of your motorcycle's engine, it is generally recommended to use the fuel type specified by the manufacturer or fuels that are explicitly formulated for motorcycles. If you have specific concerns or requirements regarding fuel choices for your motorcycle, it's best to consult the motorcycle manufacturer or a qualified mechanic for their expert advice.
