An LPG car requires proper preparation for winter i.e. a vehicle inspection. However, it it’s not worth waiting until the last minute, because its execution will reduce gas consumption instantly and will minimize the risk of engine damage at negative temperatures. We advise you what you should pay attention to when servicing a car with an LPG system.

An LPG system service should be performed in accordance with the dates recommended by its manufacturer. The first visit to the workshop should take place after driving 10,000 km. However, if the mileage of the vehicle is small, you should go to the workshop once a year - preferably in autumn, before the temperature outside drops below zero. What should you remember when carrying out a winter service of your LPG installation?

A winter service of an LPG system step by step

One of the first steps during a winter service of an LPG installation is checking its tightness at the connections of the pipes. For this purpose, the best option is to go to a specialized car workshop, where professionals will use a portable device - the leak detector. The device will detect and locate any gaps, and indicate their existence with sound and flashing diodes.

Another important task during a winter service of the LPG system is the replacement of filters. - Filters protect the car's engine from pollution, which get into the tank with fuel during refuelling. You should remember that oily impurities can block gas injectors, thus preventing switching petrol to LPG. When the outdoor temperature drops below zero, the impurities act as glue and block the injectors pistons, thus causing the engine to stall when switching fuels. I am convinced that no driver would like to expose himself to high costs resulting from negligence and LPG installation components not replaced on time. It's worth taking care of it in advance - says Marcin Dziewiątkowski, Technical Specialist of AC S.A., manufacturer of LPG/CNG systems by STAG.

Although replacement of filters is simple and any experienced driver should be able to do it easily, in this case, it is better to rely on the knowledge and experience of mechanics who will ensure that the LPG installation settings do not change during the replacement. You should also bear in mind that ignoring the replacement of filters in a timely manner can cause serious damage - for example, increased gas consumption, power loss during acceleration, uneven operation of the engine or its stalling while running on gas. Under the bonnets of vehicles with popular 6th generation installations, i.e. with sequential gas injection, there are two types of filters - liquid and volatile phase filters, which should be replaced after driving 10,000 km.

- Spark plugs are also among the elements of the LPG system, which should be taken particular care of before winter. You should remember that the gas-powered engine operates in different conditions than in the case of petrol - mainly in conditions that additionally put the ignition system under strain. This, in turn, shortens the service life of spark plugs, and defective spark plugs will prevent the car from starting at low temperatures - adds Marcin Dziewiątkowski, Technical Specialist of AC S.A., a manufacturer of LPG/CNG systems by STAG.

The last activity to be performed during a winter service is the LPG system regulation. Failure to do so may result in the vehicle consuming more fuel than it should. This can be prevented by calibration carried out in a car workshop, where specialists use a computer connected to the car. In addition, the calibration will ensure a smooth ride and reduce the risk of inconvenient jerking, thus increasing the safety and comfort of using the car.

The above actions are sufficient for an LPG installation to work properly during the winter. Over the next 10,000 kilometres, the driver can enjoy trouble-free driving and count the savings generated by driving on cheaper and more environmentally friendly fuel than petrol.
