What is LPG / AutoGas?
Liquefied petroleum gas, also known as LPG or AutoGas, is a mixture of gases present in natural gas or dissolved in petroleum. The gaseous components of LPG at room temperature – propane and butane – are easy to liquefy, hence its name.
LPG / AutoGas is the alternative fuel for new sustainable mobility. By using LPG / AutoGas you contribute to reducing greenhouse gases and improving urban air quality. There are more than 15 million LPG / AutoGas vehicles in Europe.
LPG cars are bifuel, meaning they run on gas and petrol or diesel. In the case of petrol engines, if the LPG tank runs out, the system switches manually or automatically to petrol mode without the driver noticing, except for an indicator light. In the case of diesel systems, the electronic system ensures that the fuels are mixed in the correct proportions.
At BeGas we guarantee that all our products comply with the R67 regulation for LPG and the current R115 regulation of the United Nations Economic Commission for Europe (ECE) regarding the approval of specific adaptation systems for LPG intended to be installed in motor vehicles for use in their propulsion system. Here you can see our solutions to convert a vehicle to LPG / AutoGas.
Advantages of LPG / AutoGas
- Cheaper: its cost per litre, both in Spain and in Europe, is 50% lower than that of petrol or diesel. As consumption increases by around 10% – due to the difference in densities – the net economic saving is between 40 and 45%.
- Its incorporation into the mechanics does not imply a major modification of the engine.
- Reduction of 68% of NOx emissions and 15% of CO2, if we compare it with petrol; and 99% of particles, 96% of NOx, 50% of noise level and 10% of CO2 compared to diesel or biodiesel.
- Greater autonomy: A vehicle adapted to LPG doubles its autonomy by installing a second tank. The petrol tank remains unchanged and the driver can use both fuels interchangeably. The average autonomy of a vehicle with LPG is 500 or 600 kilometres, double if we also use petrol.
- Extensive supply network in Spain. Repsol is betting heavily on this fuel and plans to create 100 new supply points per year.
- Vehicles with LPG will be classified with a green “ECO vehicle” label – just like electric vehicles – to allow their circulation in restricted urban areas. They also benefit from discounts on road tax and registration.
- LPG complies with all the regulations required for other fuels. Its danger does not go beyond that of other flammable fuels.
Disadvantages of LPG / AutoGas
Loss of the spare wheel or part of the trunk, since it is usually the place where the new tank is placed. BeGas can offer you an anti-puncture kit (pump and sealant).
Loss of warranty regarding mechanical breakdowns by the brand.
How much does it cost to convert a gasoline engine to an LPG / AutoGas one?
This transformation has a cost ranging from 1,000 euros for a basic installation to just over double for a more attractive and compact one. There are financing options. Here you can get more information about gasoline vehicle conversions.
Can I convert my diesel engine to an LPG / AutoGas one?
Today the conversion is only available for gasoline cars. TSI, TFI, TSFI engines or cars classified as Euro 3, Euro 4 and Euro 5 can also be converted to LPG.
Is the LPG / AutoGas system reliable?
Yes, it is already a mature technology. They provide cheaper general maintenance: vehicles powered by automotive gas double the engine life due to less wear on cylinders and engine rings. The gas is cleaner, leaves less carbon deposits in the combustion and allows the engine oil to stay clean for longer. The BeGas system uses liquefied gas to provide lubrication to the combustion chamber and avoid premature wear of valves caused by other non-liquid LPG systems.
Is the LPG / AutoGas system dangerous?
No. There is the same risk with a traditional petrol tank. We recommend a periodic check every 30,000 km.
Where can I refuel?
Refuelling is done at a conventional petrol station using a procedure similar to that for petrol. The pump has a safety button that must be pressed continuously while filling the tank. There are more than 600 refuelling points in Spain. Here you can consult the network of Spanish gas stations that distribute this fuel
What documents must a gas injection system have?
With each gas injection system a document is issued stating theIt describes all the system data, the number and date of manufacture of the tank, who and when the system was installed and a valid MOT inspection. All this is handled by BeGas for the convenience of our customers and, optionally, the MOT.
How can I know how much fuel I have in the gas tank?
Each LPG system shows the availability of fuel using LEDs integrated into the LPG-Petrol switching switch.
What maintenance does the BeGas LPG gas injection system have?
Inspections must be carried out every 30,000 km. Filters are changed, a leak test is carried out and a comprehensive inspection of the system is carried out. It takes no more than two hours.
What guarantee does the BeGas LPG system offer me?
The guarantee period is 2 years or 150,000 km – whichever comes first, always under guarantee conditions.
Which vehicles are adaptable?
Gasoline vehicles that meet EURO 3, EURO 4, EURO 5 or EURO 6 approval are eligible vehicles, i.e. all vehicles registered after 1 January 2001. It is possible that your vehicle meets EURO 3 regulations and was registered before this date. If you have a gasoline car, you can request information and a quote here.
