Q. What is LPG?

A. LPG stands for Liquefied Petroleum Gas and is the generic name used for mixtures of hydrocarbons (mainly propane and butane) which is compressed to form a liquid. For Automotive use LPG is quite often called Autogas (or LPG Autogas) and is specifically designed for use in a vehicle, it is governed by the National Fuel Quality Standards Act 2000 and the Autogas Determination 2003.
LPG burns readily in air and its energy content is similar to petrol, which makes it an excellent fuel for automotive use.

Q. How long will it take to pay back the cost of installation?

This will depend on three factors: the cost of the installation, the difference in pump prices of LPG and ULP, and the number of kilometres your vehicle travels per year. You can use the quick calculator on our website as a guide to your savings.

Q. Is LPG Autogas readily available?

YES. Australia’s Autogas infrastructure has grown a great deal in recent years. There are more than 3,200 outlets across Australia and nearly half of the filling stations are in regional or rural areas. Ford Australia recently drove an LPG Fairmont around Australia (13,950km) solely on LPG which proves it is possible.

Q. Is it safe?

A. YES. LPG has been used safely in Australia for many decades. The Australian standards for LPG equipment, appliances and their installation and for storage and handling are among the world's best. Every aspect of the LPG industry is covered by a National Code or Standard and also by similar or additional State Regulations.

Modern LPG Autogas systems, feature the following safety measures:
The LPG Autogas system in today’s modern vehicle is designed to be safe: safe in use, safe to repair and even safe in a vehicle accident.

The Autogas system has a number of important safety features including:

• A 3mm welded steel pressure cylinder which is stress-tested to many times its normal operating pressure prior to being installed;

• Two electronically controlled shut-off solenoids (on cylinder and under bonnet) which stop the flow of gas to the engine if the engine stops for any reason;

• Pressure relief valves for the tank and the system, to prevent any pressure build up that may damage the system, or be hazardous;

• Double back-check valves to ensure gas tight filling;

• Sealed compartments and venting around valves and pipe-work to ensure no LPG enters the interior of the vehicle;

• Approved components to ensure long service life; and

• The support of trained personnel who comply with rigorous Australian Standards for manufacture and installation of the system, in new cars at the production line, or vehicles retrofitted after purchase.

Q. Does it help the environment?

A. Burning Autogas creates appreciably less carbon dioxide (CO2) than unleaded petrol. CO2 is the most important of the greenhouse gases which are causing long-term climate change. Overall tailpipe emissions can be as much as 80 per cent cleaner using LPG Autogas instead of petrol.

Q. Is my car suitable for an LPG conversion?

A. Most passenger motor vehicles and light commercial vehicles can be successfully converted to run on LPG Autogas. Call us today on (03) 9379 1611 to confirm

Q. Where does the fuel tank go and how will my car boot be affected?


A. Typically your installer will fit a cylindrical LPG tank in the boot of the vehicle. On utility-style vehicles the tank is usually fitted under the rear cargo tray. In most LPG fuel tank installations there will be a small reduction in cargo or luggage space.

Q. Will fitting LPG affect my vehicle manufacturer warranty?

A. Vehicle warranty is not made void by the installation of an LPG system. However, the vehicle manufacturer will not warrant the LPG system (unless fitted or endorsed by them) and manufacturer will not warrant anything that is affected by having the LPG system fitted or running the vehicle on LPG. These items are covered by the LPG system supplier and installer and are usually for 3 years or 100,000 kilometres.

Extended warranty products are also available (for a small additional charge) to cover the vehicle for longer periods. Please check with your installer for both normal warranty cover and extended warranty options. You might also like to check out the Secure Warranty web site.
