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.

What about my vehicle warranty?
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 2 years or 50,000 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.

Where does LPG come from?
LPG can be obtained from two different methods or processes.
Most commonly in Australia it is extracted directly from ‘wet’ natural gas or crude oil. Almost 80% of Australian LPG is produced from this process and includes places like Bass Strait (VIC), Cooper Basin (SA), Kwinana (WA), North West Shelf (WA) and Surat Basin (QLD).

LPG can also be obtained as a by-product of the petroleum refining process which produces around 20% of Australian supplies. There are seven local refineries - Mobil Altona (VIC), BP Bulwer Island (QLD), Shell Clyde (NSW), Shell Geelong (VIC), Caltex Kurnell (NSW), BP Kwinana (WA) and Caltex Lytton (QLD) all producing LPG.

Australia has plentiful natural supplies of LPG and in 2005 exported 1.6 million tonnes (about 3 billion litres).

Is LPG Autogas different to LPG used in a BBQ?
YES. There are two different grades or blends of LPG and they are not interchangeable. LPG Autogas is for automotive use only and will be a mixture of propane and butane. The other blend is propane, which can only be used for decanting into cylinders for barbecues, camping, caravanning and household use.

Is LPG Autogas safe?
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.

How much cleaner is LPG Autogas than diesel?
The dirty black smoke that we see coming from diesel vehicles is particulates, a known cause of sickness and death. By replacing a diesel engine with an LPG Autogas equivalent, emissions of this particulate matter would be cut by over 90%.

Why is LPG Autogas more environmentally friendly?
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.

How much is LPG Autogas?
Because LPG Autogas is excise free, it can be more than 50 cents a litre cheaper than unleaded petrol. Retail LPG Autogas prices move in a similar manner to petrol prices.
Price fluctuations reflect the highly competitive nature of the industry, with retailers discounting products to protect and gain market share at times of low demand.

Why does Autogas cost more in the country than in the city?
Additional costs are incurred when transporting LPG Autogas from coastal terminals to outlets in regional inland areas.
In addition, smaller volumes are transported to regional areas less frequently than in metro areas, so a higher premium is charged for the service, which is reflected in price per litre.
This transport premium could be as much as five times the amount to transport the same volume of petrol to the same regional outlet.

Can I drive around Australia in an LPG Autogas car?
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.

Does the Government support LPG Autogas?
In 2004, the Federal Government announced Autogas would remain excise-free until 2011. Even after that date, excise will be gradually applied in annual increments of 2.5 cents per litre until it reaches a ceiling of 12.5 cents per litre in 2015. By
