What is a LPG Gas Conversion?

A LPG gas conversion comprises of a kit that is installed (by a professionally trained installer) onto your vehicle, therefore creating a bi-fuel vehicle, which will allow the driver to safely switch between petrol and propane gas. LPG gas could be used as a sole fuel source, yet it is NOT recommended. If you run low on LPG gas you can switch to petrol easily and safely even while driving. When your vehicle undergoes a LPG gas conversion, you will start to save costs on your fuel bill, at least about 40%. This means you can recover the cost of the conversion over a short period. LPG for vehicles is called autogas.


A BRC LPG Gas Conversion works exactly the same way as any other petrol engine. Everything about your vehicle remains the same, you will just have an additional separate fueling system added with its own tank, piping, ECU and injectors. While LPG is a much cleaner fuel, there is less wear and tear on the engine and its life will be prolonged. LPG is also 100% lead-free, produces fewer emissions and causes less oil-contamination.

Combustion is cleaner so your engine will be quieter and smoother to give a more echo friendly environment.

Modern systems are now able to completely interact with most makes of petrol vehicle and you will not know whether you are running on petrol or gas without looking at the switch.


  • The conversion will result in a car that runs on both Petrol and Autogas (LPG).

  • A second independent fuel system is added to the car, which requires a dedicated tank.

  • The tank is usually fitted in the spare wheel well, and can sometimes be installed underneath the vehicle.

  • Tanks are available in different sizes to suit your individual requirement.

  • Autogas liquid is purchased by the litre and is pumped into the vehicle tank via a gas fuel pistol. It becomes a gas just before entering the combustion system.


We usually recommend that the LPG system should be serviced every 15,000 -20,000 km or every 12 months to ensure that it is working effectively. This usually involves no more than an emissions check and filter change, which normally takes about 30-40 min and is cost effective.

Servicing and repairs on an autogas system should be undertaken by a Gasdrive accredited installer who has been BRC professionally trained on LPG systems or product warranty will be lost.


The performance and operational characteristics of autogas vehicles compare very favorably with other alternative automobile fuels.

LPG has a higher octane rating than petrol so converted spark-ignition engines tend to run more smoothly. This reduces engine wear and maintenance requirements, including less frequent spark plug and oil changes. Autogas exhibits less soot formation than both petrol and diesel, reducing abrasion and chemical degradation of the engine oil.

In addition, autogas does not dilute the lubricating film on the cylinder wall, which is a particular problem with petrol engines in cold starts.

The higher octane of LPG also allows higher compression ratio, which can deliver increased engine-power output and better thermal efficiency, thus reducing fuel consumption and emissions.

With the latest generation of autogas-fuel systems, acceleration and top speed are comparable to petrol or diesel.

BRC conversion kits have been successfully used in performance cars such as BMW M5, Nissan Skyline, Mitsubishi GTO and many more.

The drivers have confirmed that they cannot tell if they are driving on petrol or LPG without having to look at the LPG switch on the dashboard.
