What is the purpose of an oil filter?

[Pluto]

An oil filter serves the function of filtering engine oil. Below is a detailed explanation: 1. As engine oil circulates within the engine, it accumulates impurities and particulate matter. The oil filter removes these contaminants from the oil. Without an oil filter, these particles would continuously circulate within the engine, accelerating engine wear. 2. Engine oil requires regular replacement. Prolonged use without replacement can increase engine wear. Each time the engine oil is changed, the oil filter should also be replaced. When installing an oil filter, it must be tightened to the specified torque; otherwise, oil leaks may occur. During routine vehicle maintenance, always use genuine parts and fluids, as counterfeit products can cause significant harm to the vehicle.
