LPG : Frequently Asked Questions
Liquefied Petroleum Gas (LPG) is the generic name used for a mixture of certain hydrocarbons, mainly propane and butane. When these mixtures are lightly compressed, they change from a gaseous state to a liquid.
LPG is colourless, odourless and heavier than air. A sulphur based chemical (ethyl mercaptan) 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.
Automotive LPG (Autogas) is not the same as the LPG used for heating or cooking (as in BBQ bottles). The quality of LPG for automotive use is higher, and it is controlled to ensure consistent vehicle performance under all driving conditions.
This very much depends on an individual's perception of value.In the past, people have tended to view the cost saving as being their primary reason for conversion. In more recent times, a growing number of people have opted for LPG because it burns cleaner and therefore outputs less exhaust emissions. LPG typically has around 10 and 15 per cent lower greenhouse gas emissions and only one fifth air toxics emissions
LPG is available at more than 3500 retail outlets around Australia. Most oil company websites have a listing on which sites have LPG, or you can also look up on the Australian LP Gas Association website. If planning a long country road trip, it is advisable to plan your refueling stops before you leave home.
The only point to remember is that in a dual-fuel application it is still necessary to use petrol regularly to ensure the petrol system components remain in working order.
