The oil filter element should be replaced every 10000 km or every year. During the operation of the engine, metal wear debris, dust, carbon deposit oxidized under high temperature, colloidal sediment, water, etc. constantly mix with the lubricating oil, which leads to the wear of the oil filter element. Changing the oil filter element irregularly will lead to the failure of the oil filter, and the oil containing impurities will enter the friction surface of the moving pair, accelerating the wear of parts and reducing the service life of the engine. Therefore, regular inspection and replacement are required.

The oil filter element is usually replaced every 10000 km or once a year, which is consistent with the replacement cycle of engine lubricating oil. It is recommended to follow the replacement cycle required by the vehicle maintenance manual. In addition, under severe environmental conditions, the replacement frequency should be adjusted according to the actual situation.

The function of the oil filter is to filter out impurities, gums and moisture in the oil and deliver clean oil to the lubricating parts. During the flow of engine lubricating oil, metal wear debris, air impurities, oil oxides, etc. will be brought in. If the engine oil is not filtered and impurities enter the lubricating oil circuit, the wear of parts will be accelerated and the service life of the engine will be reduced.

It is not recommended for the owner to replace the oil filter by himself. The oil filter is usually installed under the engine. The replacement requires lifting and some special tools. The tightening of the oil filter has strict torque requirements, which are preconditions that ordinary consumers cannot grasp. What's more, the replacement of oil filter is accompanied by the replacement of engine lubricating oil.
