Can a diesel engined vehicle be converted to run on autogas LPG?
Most four-stroke, spark ignition petrol engines can be converted to bi-fuel (LPG and petrol), including turbo and super-charged engines.
The UKLPG trade association is aware that systems are being developed to convert diesel engines to run on a mixture of LPG and diesel but they have not yet been provided with satisfactory test results for engine durability or emissions.

What is involved in converting a vehicle to run on autogas LPG?
An LPG conversion results in a bi-fuel car i.e. one that car run either LPG or petrol. A second, independent fuel system is added to the car for which a dedicated fuel tank is needed. The tank is usually fitted in the spare-wheel cavity, but can sometimes be installed underneath the vehicle. As with petrol and diesel, liquid LPG is bought by the litre and pumped into the tank via a hose and a dedicated filling point. Find out more about the conversion process here…

How do I get my car converted?
We recommend you use a UKLPG Approved Installer to do the work to ensure a safe and satisfactory conversion. Read more here…

How long does the conversion process take?
Most standard conversions take around three days. The company you use may have an LPG-fuelled courtsey car that you may use while your vehicle is being converted.

What about the vehicle warranty?
You should expect at least 12 months / 10,000 miles labour and parts warranty on the LPG system. If your vehicle is still covered by a manufacturer’s warranty, then this will almost certainly be affected by the conversion. Vehicle manufacturers can only void their warranty in respect of the parts affected by the conversion and UKLPG Approved Installers can provide additional warranties to cover these areas.
Establish with the installer the cover that he will provide and whether it is included in the price quoted.

What happens if I run out of LPG or petrol?
A converted car nearly always starts up on petrol so if you run out of petrol, regardless of if you have a full-tank of LPG, you won’t be going anywhere (trust me I know from experience).
If a LPG vehicle runs out of LPG, the vehicle will automatically switch back to running on petrol without having to slow down or turn off the ignition.
Most LPG vehicle owners keep a small amount of petrol in the petrol tank for starting up and run as much as possible on LPG to maximise the cost and environmental benefits.

Will converting my car affect its performance?
Converting to Autogas LPG can increase the power and performance of your car especially if it is a turbo model. However, generally there is a small loss in performance, but so small you won’t notice it while driving. What you will notice, compared with a diesel vehicle, is a smoother and quieter ride.

What happens if an LPG converted vehicle is involved in an accident?
The LPG tank and fuel pipes are fitted with numerous safety devices. The gas flow will automatically stop if the pipes are damaged or the engine is not running. If the vehicle catches fire, the gas tank pressure is controlled via safely venting excess pressure which will prevent the tank from rupturing and causing further damage. Tanks are about 10mm thick steel and have been crash tested to prove that in the instance of a severe impact, they will deform and not split.

Can I take my LPG converted vehicle through the Channel Tunnel?
Currently, LPG vehicles are not permitted in the Channel Tunnel. Whilst the UKLPG trade association has lobbied for change in policy, we are advised that as installation standards are not as high in some parts of Europe as in the UK, and that the operators are unable to ensure systems are fitted in a proper standard the decision has been made not to allow any LPG vehicles through the tunnel.
However, LPG vehicles are allowed on cross-channel ferries.

Is autogas LPG here to stay? Surely if it becomes popular the government will increase the duty so that the price is the same as petrol and diesel?
LPG autogas is currently the most viable option as an alternative vehicle fuel in the UK. The LPG industry, together with the government and drivers using LPG, has invested around £1/4 billion in creating a healthy market for vehicle LPG. The industry has a total annual turnover in excess of £500 million and employs around 15,000 people. There are approximately 160,000 LPG powered vehicles in the UK (out of a vehicle population of over 30 million) and more than 12 million worldwide.

In accordance with the UKLPG trade association Industry Information Sheet 028, user owned, portable LPG cylinders may be permitted to be re-filled at an autogas refuelling site provided they:
- remain in-situ for refuelling; and
- are fitted with a device to physically prevent filling beyond 80%; and
- are connected to a fixed filling connector which is not part of the vessel.
If your portable cylinder does not meet all three criteria above, you will not be allowed to refuel it at any Autogas Limited site.
