The function of the oil filter is to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine. The oil filter element can filter out harmful impurities in the oil and keep the oil clean, thereby extending the service life of the engine.

The oil filter element has the function of filtering engine oil:
1. When the oil circulates in the engine, there will be some impurities and particles. The oil filter element can filter out the impurities and particles in the oil.
2. Without an oil filter, particles in the oil will continue to circulate in the engine, which will increase engine wear.
More introduction to oil filter elements:
1. When installing the oil filter element, be sure to tighten it to the specified torque, otherwise it will cause oil leakage.
2. The upstream of the engine filter is the oil pump, and the downstream is the various parts in the engine that need lubrication.
