What is LPG?
LPG stands for Liquefied Petroleum Gas and is referred to as 'Autogas' when used as an automotive fuel.
It is the 3rd most commonly use fuel behind petrol and diesel with over 10m vehicles running on LPG in Europe alone.
How do I refuel?
Refuelling is quick and easy. We'll provide you with a demonstration when your cab is converted.
What happens to my spare wheel and wheelchair ramp?
The wheelchair ramp is placed in a cover and stored in the front of the cab. We also provide a tyre repair kit to ensure that you are not stuck on the side of the road in the event of a puncture.
Is LPG safe?
Yes. Autogas equipment must conform to the same safety tests as conventional fuel systems and is often considered to be safer than petrol or diesel.
What are the benefits?
LPG (Autogas) is cleaner burning and cheaper than petrol or diesel. It is highly practical as their is no range anxiety or lengthy refuelling times.
How much can I save?
LPG is around 25% less efficient than diesel but typically half the price. Therefore, you can save between 20-30% off your fuel bills.
Where is the vehicle converted?
The conversion takes place at our facilities in Alcester (B49 6EX)
How long does it take?
The conversion typically takes 8 working days can take longer if there are unforeseen delays.
What is the servicing schedule?
The vehicle is serviced at 12,500 mile intervals. Details of the servicing schedule are contained in the manual that we provide to you.
Will the price of LPG go up?
The price can increase and decrease like other fuels, however the current Fuel Duty Differential ensures that the price difference is maintained until 2032, guaranteeing savings.
What engine do you install?
The diesel engine is replaced with a brand new 2.0ltr turbo petrol-LPG engine from General Motors (Vauxhall). See 'system specifications' below for more information.
*Worldwide harmonized Light vehicles Test Cycles (WLTC) **depending on model TX2/TX4
Has the system changed?
Following the original 65 cabs converted under the Birmingham NOx Reduction Champions' project,, we've made a number of enhancements to further improve performance and durability. For example, we rebuild the engine with dedicated LPG valve seats, we've improved the software and have added NOx sensors.
Are there grants available?
There are grant schemes available for licensed cab drivers in Birmingham, London and Scotland. See our Birmingham and London pages for further details.
Do you offer finance?
We do not currently offer any finance options.
Can local authorities pay the grants directly to VRS
Depending on area, check the terms with your local authority.
What models can be converted?
We have approval to convert TX1, TXII and TX4 cabs.
How do I know if my vehicle is in a suitable condition?
The vehicle should be in good working order when it arrives to our workshop for the conversion. If there any known issues that would result in MOT failure or cause potential problems (e.g. wheel bearing), these should be rectified prior to the conversion.
! The LPG tank is secured in the boot space. The boot space should be free of any rust. If there is rust present, this should be repaired to the appropriate standard i.e. welding.
! The new engine is assembled to the existing gearbox. The gearbox should therefore be in a suitable condition. If the gearbox needs replacing, we can do so during the conversion process.
If in doubt, please get in touch for further guidance.
Will I have air conditioning?
We are currently developing an air conditioning system for our engine as it is not possible to use the original parts.
It will only be available for TX4 cabs that had air conditioning in the first instance.
It can be retrofitted at a later date for an additional cost (to be confirmed upon approval).
What if my vehicle is not driveable?
If your vehicle is not driveable (due to engine failure, for example), we may still be able to convert the vehicle, however, we will not be able to complete our initial inspection and road tests.
How does the performance change?
The new engine is downtuned to optimise performance and provide a similar driving experience. However, the new engine will feel more powerful as well as being smoother and quieter.
Is the system easy to operate?
Yes. The LPG system is easy to use and switches automatically. A switch is installed to enable the driver to switch between fuels automatically.
How do I switch between fuels?
When the vehicle is in 'petrol mode' the orange LED will be displayed next to the petrol pump symbol. To switch from petrol to LPG, simply push the button in the centre of the switch when the ignition is on.
Once pressed, the green LPG LED will be lit next to the G (which stands for Gas) to indicate that the vehicle is now running on LPG.
If the engine is cold, the green LPG LED will be flashing and the orange petrol LPG will be lit. This means that the vehicle is running on petrol. When the engine has warmed up, the system will automatically switch to LPG. The green LPG LED will be lit continuously and the orange petrol LED will turn off.
The vehicle can be switched back to petrol by pressing the button in the centre of the switch. The orange petrol LED will be lit to indicate the vehicle is using petrol.
NOTE: If LPG is preselected, the system always starts on LPG. Only during a cold start will the engine start in petrol and then switch automatically to LPG.
How do I know how much LPG I have left?
There are 5 LED lights on the left side of the switch to give you an indication of how much LPG is in the tank.
4 green LED lights = Full tank of LPG
3 green LED lights = 3/4 full
2 green LED lights = 1/2 full
1 green LED light = 1/4 full
When the red LED is lit, there are reserve levels of LPG left in the tank
If the LPG tank runs empty, the vehicle will automatically revert back to petrol mode. The orange petrol LED will be lit and an acoustic sound will notify you that the vehicle is using petrol.
Press the central button to stop the acoustic sound (Note: when you refuel the LPG tank, press the central button to put the system back into 'LPG Mode').
