What is autogas/LPG?

Autogas (engine gas, gas oil) or Liquified Petroleum Gas (LPG) consists mainly of propane (C3H8) and butane (C4H10). These gases, which are gaseous under normal atmospheric conditions, are obtained during the distillation of crude oil. The product obtained is then liquefied under pressure to be stored, transported and refueled.


In Belgium, for autogas, the distribution between propane and butane in the winter is 70/30 and in the summer 60/40.

  •  Not only is autogas good for the environment, it is also perfectly safe

This higher octane number means that Autogas ignites more evenly. Unlike other fuels, no additives are required to ensure high quality.
