How much engine oil should be added to a BMW 523li?
1 Answers
BMW 523li requires approximately 5 liters of engine oil. Reasons: The BMW 523 equipped with the N20 engine only needs 5 liters of oil, while the six-cylinder version requires 6.5 liters. Function of engine oil: Engine oil not only lubricates the engine but also performs cleaning, sealing, buffering, rust prevention, and heat dissipation. During engine operation, the oil forms a protective film on the surfaces of various engine components, preventing direct contact and friction between them. Precautions: Engine oil needs to be changed regularly as its performance degrades over time. When changing the oil, replace the oil filter as well. The oil filter is used to clean the oil; without it, the oil would become very dirty after some use.
