What does the term 'propane autogas' refer to?

The term 'propane autogas' specifically refers to propane that is utilized as a fuel for vehicles. This application of propane is significant because it serves as an alternative fuel that can reduce emissions and reliance on gasoline or diesel. Vehicles designed or modified to operate on propane autogas can enjoy benefits such as cleaner combustion and lower overall emissions when compared to conventional fuel sources.

While propane can indeed be used for various purposes such as heating, cooking, or being mixed with other fuels, these applications do not align with the specific definition of autogas. Therefore, the focus on its use as a vehicle fuel clearly distinguishes it as the correct interpretation of the term.
