The feature of the oil filter is to remove particles, colloids and moisture in the oil and provide easy oil for each lubricating part.
The oil filter can reduce the frictional resistance of engine components and reduce component wear. Engine oil itself is composed of a large amount of colloids, impurities, moisture and ingredients. At the same time, as the engine runs sooner or later, the introduction of metal particles, the entry of impurities in the air, and the production of oil oxides gradually increase the types of impurities in the oil. If the oil immediately enters the lubricating oil circuit without filtering, the debris contained in the oil will be brought to the friction surface of the transmission pair, which will increase the wear of the components and reduce the service life of the engine.
