What are the costs of an LPG Conversion?

Subject to space limitations most unleaded petrol vehicles can be converted to LPG at a reasonable cost. There are 2 types on systems installed;

Sequential Vapour Injection- Where a LPG injection system is installed

The SVI is an electronically controlled LPG system that has its own Electronic Control Unit (ECU.) The ECU controls the LPG injectors which are fitted directly to the inlet manifold of each individual cylinder. This allows for a precise mixture which optimises the combustion process. The SVI allows for a seamless transition from petrol to LPG and back. This system minimises the power loss as the closed loop operation electronically controls the LPG vapour injection.

Simple Ring Mixer- Used on carburettor vehicles this is more basic and does not create the advantage of individual cylinder injection. As a result these are installed on older vehicles and are cheaper to install.

The 2 types of systems range from about $2000 to $4500 installed depending on the type of vehicle, type of system and additional options. When comparing conversion quotes it is important that you compare quotes for the same system to get a valid comparison. First Class Taxis offer a FREE first service and extended warranty for regular servicing. There is also a range of tank sizes and locations that need to be considered.

What does the LPG conversion involve?

During most conversions;

  1. A steel LPG storage tank will be installed, usually in the boot, spare wheel well or underneath on vehicles with high ground clearance eg. Four wheel drives. The tank will be fitted with an Automatic Fill Limiter (AFL) this ensures you can not fill your tank past the safe limit of 80%. This is necessary as LPG requires room to expand with temperature changes.
  2. A converter/regulator is added. This converts the liquid gas into a gaseous vapour, as well as regulating the process.
  3. A special air/fuel mixer is installed to ensure the correct amounts of LPG to Air are mixed together during combustion.
  4. Most advanced systems incorporate LPG injection rather than a simple mixer. Such systems provide more precise control of the LPG but are more complex and expensive to fit.
  5. A fuel lock is fitted that lets fuel flow when the engine is running but shuts off the fuel supply as soon as the engine stops.
  6. If the vehicle is post 1986 it must be fitted with an LPG Fuel Control Processor.

Vehicle Storage Tanks

All LPG vehicle storage tanks are manufactured to comply with Australian Standard AS 3509 and installed to meet Australian Standard AS 1425. The tank MUST be re-tested every 10 years from date of manufacture. First Class Taxis is an Approved 10 year tank testing station.

Normal servicing is unaffected by the conversion however in Queensland there are strict controls on the quality of installations, only licensed LPG installers may work on LPG systems this includes regular maintenance and servicing.

Dual Fuel or Dedicated LPG Only

Dual Fuel means that the vehicle can operate on either one of two fuels, usually petrol or LPG. It costs no more to have your vehicle converted to dual fuel than it does to be converted to dedicated LPG. So it makes sense to go Dual Fuel and give yourself the flexibility to be able to use two types of fuel. The petrol tank will remain in the vehicle and the driver can change to LPG or petrol or vice versa via a switch usually located on the dashboard.

Will my vehicle warranty be affected?

Vehicle warranty is not made void by the installation of an LPG system. However the vehicle manufacturer will not warrant the LPG system (unless endorsed by them) and the 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.
