What is LPG?

Autogas is the term generally used for Liquefied Petroleum Gas (LPG) when it is used for the propulsion of road vehicle.


LPG 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 of approximately 4 million tonnes per annum is currently available from the North Sea. The surplus is forecast to increase over the next 20 years.


When it is pressurised 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 rating (RON). For example, Super grade petrol is 98 octane , ordinary Lead Free petrol is 95 octane. LPG is over 100 octane.
