How many kilometers should a private car generally change its oil?
2 Answers
Private cars generally change their oil every 10,000 kilometers. The following are specific explanations about private cars: 1. Meaning: The so-called private car is a concept from Hong Kong, mainly referring to household vehicles purchased by individuals, with the right to use and control, and can be freely used and controlled without breaking the law. Whether a car is a private car or a public car is determined by the identity of the owner when registering at the vehicle management office. If it is registered in the name of an institution, group, or unit, it is a public car; if it is registered in the name of an individual, it is a private car, and the ownership belongs to the individual. 2. Classification: Mini cars (displacement below 1L), ordinary cars (displacement 1.0~1.6L), intermediate cars (displacement 1.6~2.5L), mid-to-high-end cars (displacement 2.5~4.0L), and high-end cars (displacement above 4L).
When I first bought my car, I was really confused about oil changes and asked a lot of experienced drivers and mechanics. Generally, private cars are recommended to change oil every 5,000 to 10,000 kilometers, depending on the model and usage. For example, my sedan's manual states that with full synthetic oil, it should be changed every 10,000 kilometers. However, if you frequently drive in city traffic or take short trips, the engine works harder, so I usually get it serviced at around 8,000 kilometers. Checking the oil level is also crucial—if the oil is black or has metal particles, it means it's degraded and should be changed sooner. If you drive a lot on highways, the oil can last longer, but don't get too complacent since oil protects the engine, and once it fails, repair costs can be high. I recommend that beginners check their oil every 6,000 to 8,000 kilometers to develop a habit and avoid future issues. Also, remember to choose a good oil brand, like major manufacturers' synthetic oils, which can extend the interval between changes.
