How often should a BMW be serviced?

[NathanMarie]

BMWs should be serviced approximately every 10,000 kilometers. The purpose of car maintenance is to filter impurities from the engine oil and gasoline, preventing them from entering the engine and affecting its normal operation. Regularly replacing these components can effectively extend the engine's lifespan, maintain the car's appearance and cleanliness, ensure normal technical conditions, eliminate potential hazards, prevent faults, and slow down the deterioration process. Taking the 2021 BMW 3 Series as an example, its body dimensions are: length 4719mm, width 1827mm, height 1459mm, wheelbase 2851mm, fuel tank capacity 59 liters, and the body structure is a 4-door, 5-seater sedan.
