Gas conversions and Dual Fuel

Gas conversions and dual fuel

Livesey’s Motor Works are qualified and experienced mechanics, able to install and service LPG gas conversions to make your petrol or diesel vehicle run on LPG gas.

What is an LPG conversion or dual fuel?
An LPG conversion involves fitting a second tank (a LPG tank) to your vehicle. This allows your car to run on two fuels – the original fuel (petrol or diesel) and LPG. It’s also known as dual fuel.

Today, there are basically two types of LPG Conversions on the market; Vacuum Induction or Gas Injection. Gas Injection costs more, but in most cases it produces more power and economy. The type of conversion that you use depends on the vehicle you own, how much you want to spend and what you use the vehicle for.

What is LGP Fuel?
The quality of LPG for automotive use is controlled to ensure consistent vehicle performance under all driving conditions. The gas is liquefied under moderate pressure. When allowed to revert to vapour it expands 270 times its liquid volume.

This enables LPG to be stored as a compact liquid but burnt as a dry gaseous vapour. LPG is non-corrosive, free of lead and heavier than air. It is produced by refinery fractionation of oil or is stripped from naturally occurring Natural Gas.

Why convert your vehicle to LPG or dual fuel?
The biggest benefit of an LPG Conversion is the savings in fuel. For most conversions you can achieve a 40 to 50% saving in fuel when running on LPG. For example, if you drive around 15,000km per year; that would be a saving of around $1000 per year. This might not seem like a lot, for those who drive more than 15,000km a year it becomes significant.

An LPG Conversion also gives you much better range (almost double in most cases), it allows the engine to run cleaner and it adds value to your vehicle. It also reduces the vehicle’s emissions, which is partly why it was encouraged in Australia through rebates.

What are the environmental advantages of using LPG?
LPG is better for the environment. Compared to unleaded petrol, it creates about:

  • 15 to 20% less greenhouse gases
  • 30 to 40% less volatile organic compounds and oxides of nitrogen
  • 50 to 60% less carbon monoxide
  • 80% less toxic air pollutants such as benzene and sulphur oxides (

Diesel Gas systems
A Diesel Gas system runs on around 85% diesel and 15% LPG. The benefits include significant power increase, better economy and better range. The power increase is usually related the same as fitting a turbo to your vehicle. Diesel Gas systems only require a small LPG tank (a big four wheel drive usually only needs a 30 to 45 litre gas tank) to match the long range diesel tank.

Are Government rebates available?
Government rebates on conversions are available on some conversions, please contact us to discuss what options are possible and rebates involved.
