LPG dual-fuel conversions for Land Rover petrol engines. Popular for V8 Range Rovers — significantly reduces running costs.
LPG conversion is one of the most cost-effective modifications available for high-consumption Land Rovers, and Davis Performance Landys has been installing certified LPG systems across our South Windsor workshop for many years. With LPG typically priced 40–50% below petrol per litre, the economics are straightforward — particularly for larger-engined Land Rovers that cover significant annual kilometres.
The Range Rover V8 — in both the Classic and P38 variants — is the most popular Land Rover model we convert. The reasons are simple: the engine has a large displacement, fuel consumption is high, and the vehicles are predominantly used on-road where LPG infrastructure is accessible. Owners driving 20,000 km per year or more typically recover the cost of conversion within two to three years, with substantial ongoing savings thereafter.
We install bi-fuel systems, meaning the vehicle retains full petrol capability and switches automatically between fuels. This eliminates range anxiety in areas where LPG availability is limited — including remote parts of regional NSW.
Diesel LPG (or diesel-LPG dual-fuel) systems are also available. These introduce LPG into the intake alongside diesel, reducing the amount of diesel consumed per kilometre. They are particularly relevant for heavy-duty diesel Land Rovers covering high highway kilometres across the Hawkesbury and Western Sydney regions.
Our workshop at 18/62 Argyle St, South Windsor is accessible from Penrith, Richmond, the Hills District, and across the broader Western Sydney region. With over 30 years of Land Rover-specific experience and 4.9 stars from 184 Google reviews, we have the expertise to advise whether LPG conversion is the right investment for your specific vehicle and driving pattern.
LPG is typically 40–50% cheaper per litre than unleaded petrol. The exact saving depends on your fuel consumption and annual kilometres. A Range Rover V8 averaging 16–18 L/100 km and covering 20,000 km per year can save $2,000–$3,000 annually at current fuel prices, meaning most conversions pay for themselves within two to three years.
A properly calibrated bi-fuel system produces minimal power difference on LPG versus petrol. Some owners notice a slight reduction in peak power, which is normal due to LPG's different energy density. Throttle response and everyday driveability remain comparable. Post-installation tuning is included with every conversion we carry out.
Yes. We fit bi-fuel systems that allow the vehicle to run on either LPG or petrol, switching automatically when one tank is empty. The petrol tank and all original fuel system components are retained. This is the standard approach and is essential for travel in areas with limited LPG availability.
Yes, LPG conversions are legal in NSW when installed to AGA certification standards. All conversions we perform include full compliance documentation. The system must be declared and inspected as part of the vehicle's registration record. We handle the certification process as part of the installation.
The Range Rover V8 (Classic and P38) is the most popular due to its high fuel consumption making the economics very favourable. Petrol Defenders and Discovery 1 models are also suitable. Diesel models can have dual-fuel LPG induction systems fitted. We assess each vehicle individually to confirm suitability before quoting.
A standard bi-fuel petrol LPG conversion typically takes two to three workshop days. This includes installation, system calibration, tuning, and a road test to confirm correct operation across the full rev range. We advise booking in advance as conversion slots are in demand.
