When
the engine operates, its speed can be reached to thousands of
revolution per minute. The moving parts need to lubricate so that the
engine can work normally. During the lubrication, the meal
debrist,dust,carbon deposition and water and other impurites will be
mixed into the oil. It will increase the wear parts, leading to
premature engine failure.
In the oil circulation lubrication process,the oil filter is used to filter the impurities in the lubrication oil to clean the engine oil for work and improve its service life.
It has outer body for most oil filter.
But for some models, it just needs to change the inner elements.We
should replace the oil filter every 5000km. Under normal circumstances,
the oil filter and oil will be replaced together.
