It is also possible to use propane in a diesel, not as a complete substitute for oil but at about 20%. This is said to improve emissions and economy.

Gas conversions are popular in the UK, where a government grant is available towards the conversion of a new, or nearly new car. Almost all of the light commercials on our fleet (local government) are dual fuel, running on both petrol (gasoline) and liquified petroleum gas (propane).
