What is LPG Autogas?
LPG stands for Liquefied Petroleum Gas and is the generic name used for mixtures of hydrocarbons (mainly propane and butane). When these mixtures are lightly compressed (approx.800 kPa or 120 psi) they change from a gaseous state to a liquid. LPG is colourless, odourless and heavier than air. A chemical is added to give it a smell like rotten cabbage, so that even a very small leak can be easily detected. LPG burns readily in air and has an energy content similar to petrol, which makes it an excellent fuel for heating, cooking and for automotive use. Automotive use LPG is quite often called Autogas (or LPG Autogas) and is specifically designed for use in a vehicle. LPG Autogas can contain both propane and butane with the specification (or blend) governed by the requirements of the National Fuel Quality Standards Act 2000 and the Autogas Determination 2003.
