How is the first car maintenance time calculated?

[KylieMarie]

How to calculate the first car maintenance time: The first maintenance time is calculated based on the purchase invoice date. For new cars, the first maintenance is usually determined by either the mileage or the specified first maintenance time, whichever comes first. Therefore, even if the mileage is insufficient when the time arrives, the first maintenance should still be performed. Generally, the first maintenance time for cars ranges from 3 to 5 months, with the first maintenance mileage between 3,000 to 5,000 kilometers, and for some cars, it can even extend up to 8,000 kilometers. This variation is due to differences in the specific technical conditions of the vehicles. The engine has a break-in period for new cars, and different brands and models of cars are equipped with different engines. Some engines use special technologies and have strict requirements for oil, while others have unique materials and high precision, resulting in relatively less wear.
