How often should the oil filter be replaced?
On average, every 7,000 to 10,000 km. However, the service life of this consumable may be reduced if the engine is constantly operated under high loads, low-quality oil is used in the lubrication system, or antifreeze gets into it due to loss of tightness. Premature wear of the part may also be caused by the engine overheating, after which the engine oil and filter need to be replaced.
What happens if you never replace the oil filter?
The design of the oil filter has a special bypass valve to prevent oil starvation of the motor. It opens when you start a cold engine, in case of high oil viscosity, extremely high pressure in the lubrication system, or when the filtering element is clogged and its performance is significantly reduced. If you haven’t changed the oil filter for a long time, impure oil will constantly be delivered to the engine. This leads to increased formation of carbon and sludge deposits on engine parts, oil channels clogging, and rapid wear of the piston-cylinder group.
How do I change the oil filter?
First, you need to raise the car or place it over an inspection pit. Immobilize it using the handbrake. The engine should be warmed up slightly. Then unscrew the drain plug of the oil pan and drain the waste oil into a prepared container. Be careful: the oil is hot. After that, depending on whether your filter is of a cartridge type or not, you have to unscrew the filter housing or remove the filtering element from the housing. Cover the car body with a cloth to keep it clean. Lubricate the seal of the new filter with engine oil. The filter itself should also be filled with lubricant before installation. Next, clean the oil pan and screw in the threaded plug with a new o-ring on it. Then pour in the fresh oil to the correct level, start the engine, let it run for a while, and check the oil level with the dipstick to top up as necessary.
