How Long Can an Oil Filter Last?

[DaniellaAnn]

The service life of an oil filter is 5,000 kilometers. Here is a detailed introduction to the service life of an oil filter: 1. Most oil filters nowadays are of the spin-on type, featuring a round metal casing that encloses folded filter paper. This filter paper is the core material of the oil filter, capable of withstanding oil pressure and resistant to deformation. 2. The oil filter is screwed into the middle section of the oil circuit, positioned between the oil pan below and the engine above. Its primary function is to filter out impurities and contaminants from the oil, providing clean lubricating oil to the engine, reducing wear, and extending the engine's lifespan. 3. The oil filter has an inlet and an outlet. Oil from the oil pan flows into the filter through the inlet check valve. The dirty oil enters at the edge of the filter, on the outer side of the filter paper, and is then filtered through the paper. Clean oil flows out from the center of the filter and is sprayed onto various engine components.
