The maintenance price of BMW x5 is around 65,438+0, 500 yuan, using original engine oil parts. The effect is not very good, so the overall cost performance is not very good, and personally it is not worth it. After doing it twice again, I went outside to repair it in the garage. Better parts can be exchanged at lower prices. For example, the oil added now is imported GT? Magic? Force? The engine oil is of good quality and is the base oil of four types of PAO. Good anti-aging ability and long maintenance mileage. In addition, there is liquid molybdenum component, which has anti-wear protection and good driving power. It is much smoother to drive than the original factory, and it is more practical to maintain than the 4s shop.
