Where is the oil filter located in a BMW 5 Series?
1 Answers
The oil filter in a BMW X5 is located on the right side of the wiper cover plate, which can only be seen after opening the engine hood. The oil filter is designed to remove impurities, gum, and moisture from the engine oil, delivering clean oil to all lubrication points. During car maintenance, changing the engine oil is the most commonly heard task, but the oil filter is often overlooked. The service life of an oil filter is approximately 5,000 kilometers, and its replacement depends on the cleanliness of the engine oil. Oil Filter: If there are excessive impurities or sludge in the oil, they can adhere to the filter paper, clogging the filtration pores and causing a drop in oil pressure. This allows contaminated oil to enter the engine directly, indicating that it's time to replace the oil filter. The oil filter removes impurities from the oil, reducing friction between moving parts in the engine and minimizing wear. Clean oil is continuously delivered to the friction surfaces of moving parts, forming a lubricating film for smooth operation. Precautions: Engine oil inherently contains a certain amount of gum, impurities, moisture, and additives. During engine operation, the introduction of metal wear particles, airborne contaminants, and the formation of oil oxidation products gradually increase the impurities in the oil. If the oil is not filtered before entering the lubrication circuit, these impurities can be carried to the friction surfaces of moving parts, accelerating wear and reducing the engine's service life.
