What is an oil filter?

The oil filter element is the oil filter. The function of the oil filter is to filter out debris, colloids and moisture in the oil, and to deliver clean oil to each lubricating part.

In order to reduce the frictional resistance between the relative moving parts in the engine and reduce the wear of the parts, the oil is continuously delivered to the friction surface of each moving part to form a lubricating oil film for lubrication. The engine oil itself contains a certain amount of colloids, impurities, moisture and additives. At the same time, during the operation of the engine, the introduction of metal wear debris, the entry of sundries in the air, and the production of oil oxides gradually increase the sundries in the engine oil. If the oil is not filtered and directly enters the lubricating oil circuit, the debris contained in the oil will be brought to the friction surface of the moving pair, which will accelerate the wear of the parts and reduce the service life of the engine.

The oil filter maintains continuous oil flow and removes particles (dirt, oxidized oil, metallic particles) that may appear in the motor oil due to engine wear. It purifies the motor oil so that it can do its job efficiently. An oil filter has enough contaminant holding capacity to remain fully functional until the next oil change.
Reasons to change your oil filter:
To reduce engine wear:
A failing oil filter will allow impurities to pass through and slow down the arrival of oil, which can lead to early engine wear, poor performance or even engine failure.
To avoid soiling your new oil:
The oil filter should be generally be changed at each oil change (every 10,000 km for a petrol car and every 15,000 km for a diesel) to avoid soiling your new oil.
