What is the purpose of an oil filter?
2 Answers
The functions of an oil filter are as follows: 1. The oil filter can filter the engine oil. As the oil circulates within the engine, it inevitably accumulates some impurities and particles. The oil filter removes these impurities and particles from the oil. Without an oil filter, the particles in the oil would continuously circulate within the engine, accelerating engine wear. 2. The oil filter helps maintain the cleanliness of the oil, ensuring that the oil can provide adequate lubrication to the engine. 3. It affects the oil change interval. Prolonged use of old oil can increase engine wear. The oil filter should be replaced every time the engine oil is changed. Below is some relevant information about oil filters: 1. When purchasing an oil filter, always choose genuine products from reputable brands. 2. When installing the oil filter, tighten it to the specified torque to prevent oil leaks. 3. During regular vehicle maintenance, always use genuine parts and fluids to avoid significant harm to the car.
The oil filter acts like the kidneys of an engine, responsible for filtering out contaminants such as metal debris and combustion carbon deposits from the oil. You see, when the engine runs, friction between parts generates a large number of tiny metal particles. If these aren't filtered out, they become 'invisible killers' that damage the machine, causing scratches on cylinder walls and bearings. Last time I disassembled an old car that had run 80,000 kilometers without changing the filter, the oil pan was full of black sludge, and the crankshaft was nearly worn with grooves. The special filter paper inside the filter is crucial—it can trap impurities finer than a strand of hair, but it becomes saturated and clogged if used beyond the oil change interval. Remember to replace the filter every two oil changes; this is the key secret to keeping the engine vibrant.
