Manuals and tips on repair and maintenance for Filters

All filters in the car need to be replaced periodically. These include the engine oil and air filters, as well as the transmission, fuel and cabin filters. In diesel engines, there is also a particulate filter which should be changed.

The particulate filter doesn’t have a prescribed replacement interval and should be changed as necessary. All other parts are to be replaced strictly according to the schedule specified by the car manufacturer. The oil filter is changed at the same time as the motor oil, on average every 10,000–15,000 km. The automatic transmission filter, together with the transmission fluid, should be renewed every 60,000 km, and that of the manual gearbox every 80,000 km. The lifespan of the air filter cartridge is up to 10,000–15,000 km. However, if you drive in a dusty area, the service life of the part is halved. A new cabin filter should be installed twice a year: before the beginning of spring and autumn.

A clogged oil filter leads to accelerated wear of engine components, while a bad fuel filter leads to unstable engine operation and reduced torque. If you don’t stick to the air filter replacement intervals, the fuel consumption increases and the engine power output decreases. A worn-out cartridge of the cabin filter impairs the passenger compartment ventilation and cannot prevent dust and unpleasant odours from getting inside. Using a bad transmission filter reduces the service life of the transmission.
