Liquefied Petroleum Gas ( LPG )
As An Automotive Fuel

Autogas is the term generally used for Liquefied Petroleum Gas (LPG), when it is used for the propulsion of road vehicles. It is obtained as a by-product of the distillation of oil from crude oil and from “wet” North Sea gas. It is produced in large quantities. A surplus, (to increase over the next 20 years), of approximately 4 million tonnes per annum is currently available from the North Sea.

When the gas is pressurised to approximately 7 bar it becomes a liquid and it is in this form that it is pumped into your tank. Compared to petrol, Autogas has a higher octane content (see RON method – Super grade petrol 98 – Lead free 95 – LPG over 100 octane).

Advantages over other fuels:

  • Autogas as a fuel, is pure gas and is not subject to a cocktail of chemical additives like petrol.

  • The environmental benefits are clear; not only is carbon dioxide output reduced so particulates are virtually eliminated.

  • Because it is already in gaseous form when it enters the combustion chamber, Autogas burns more efficiently than liquid fuels.

  • The life of the engine is extended as a result of the absence of acids and carbon deposits.

  • Autogas, unlike petrol, will not dilute the engine oil, thus increasing engine protection between services.

  • Unlike diesel, you do not have to adjust your driving style. Cold starting is no problem.

  • Engine performance is almost exactly the same as with petrol.
  • Autogas eliminates the possibility of theft once in the vehicle, this problem costs companies millions every year and is set to rise.

  • Its weight by volume is half that of water.
