• Almost all unleaded petrol-fuelled vehicles can (subject to space limitations) be converted to LPG Autogas operation at a reasonable cost. Systems range in price from about $2,500 to $4,500 installed, depending on the type of vehicle, type of system and additional options. A KIT LISTING of suitable vehicles is now available. (Note: This is not a complete list and will change as we receive more information from LPG equipment suppliers. Use this list only as a guide and consult your installer/equipment supplier for the most up-to-date information.)


• The much lower cost of Autogas compared to unleaded petrol (typically half the price or less) means the cost of conversion is quickly paid back. For example if over the course of a year Autogas averaged 70 cents per litre, while unleaded petrol averaged $1.40 per litre, a six cylinder car driver traveling 25,000 kilometres a year on Autogas would save $1,942 – the equivalent of $37 per week. Assuming the system cost $2,500 to install, it would take just 16 months to pay for itself. To work out how long it will take to recoup the cost of converting your vehicle to Autogas, use our PAYBACK CALCULATOR on the right hand side of the page. Calculations exclude the benefits of Federal (and State) Government grants (rebate).


• Autogas systems fitted by an installer after new vehicle purchase are generally warranted by the installer and the equipment supplier. The terms and conditions of the warranty vary so you should check these before purchase. Extended warranty period options are now available through some installers.


• The Industry Association (LPG Australia) has issued a CODE OF PRACTICE for fitting LPG equipment to a motor vehicle and you should ask your installer if he follows the principles set out in the Code. To find an installer near you click on installer link at right. Other installer lists are available by clicking on the following state links - WA - QLD .


• Dual-fuel Autogas systems allow the vehicle to operate on either LPG or unleaded petrol. This can almost double the vehicles range. The petrol tank still remains in the car and the driver can switch from gas to petrol or vice-versa.


• Running your engine on Autogas is beneficial to your car. LPG is a cleaner burning fuel than petrol, so engine life is actually extended. Engine oil and spark plugs need changing less often when running on Autogas, so service intervals can be increased.


• The time taken to install an Autogas system varies depending on a number of factors including tank options, the number of cylinders and so on. A typical family sedan with a single boot-mounted tank should take one to two days, whilst a large four-wheel drive with multiple tanks might take two to three days.


• Your insurance company should be informed of the modification to Autogas, and you should ask them to revise the sum insured to reflect the cost of the system.


• In addition to the long term savings the Federal Government now offers grants for private motorists of $1,000 for purchase of a factory-fitted LPG vehicle and $2,000 for conversion of a new or used vehicle to LPG. For more information go to Govt Grants for LPG

• In addition the Western Australian State Government has recognised the benefits of Autogas by also offering a $1000 rebate for vehicle conversion or purchasing an Autogas vehicle. For more information go to the WA DPI Web Site

• In the ACT, the government gives a 20 per cent concession on your registration if you have an Autogas vehicle. For more information go to the ACT Registration Web Site

Operators of commercial vehicles and buses weighing 3.5 tonnes or more, may be eligible for assistance for the purchase, conversion, or upgrade of vehicles to operate on Autogas under the Alternate Fuels Conversion Program.

Administered by the Australian Greenhouse Office, the program provides up to 50% of the costs of:

• converting conventionally-fuelled vehicles
• upgrading existing Autogas fuel systems
• the difference between the purchase price of a new Autogas-fuelled vehicle and the price of a conventionally-fuelled vehicle

The aim of the program is to significantly reduce greenhouse gas and other emissions in the transport sector. For more information about the program, contact the Australian Greenhouse Office or go to www.greenhouse.gov.au

You should note that any vehicle compliance-plated after December 2003 that is converted to run on Autogas must be fitted with a system that has passed current emissions test standards. For a list of emission tested systems click on the vehicle logos at the top of this page.

An alternative to converting an existing vehicle is to buy a factory-fitted or dedicated LPG vehicle. See PURCHASING A NEW VEHICLE.
