How many kilometers should a new car run before breaking in on the highway?

The break-in mileage for a car is generally between 1,000 to 2,500 kilometers, while imported cars may require a longer distance, typically between 1,500 to 3,000 kilometers. The break-in period is divided into three stages: the initial 100 kilometers, the early break-in phase of 200 kilometers, and the formation of an oxidation film at 3,000 kilometers. Here is some relevant information: 1. Precautions during the break-in period: Avoid emergency braking during the break-in period, as it can impact the braking system. Also, avoid overloading the new car, as running it at full capacity during the break-in period can damage the components. Additionally, avoid long-distance trips during the break-in period, as prolonged engine operation can lead to increased wear on the components. 2. Concept of the break-in period: Before assembly, each moving part of the car is individually manufactured, and there may be geometric deviations in the machining process. As a result, some moving parts may have direct contact in certain areas after assembly, making it difficult for lubricating oil to reach the friction surfaces, leading to early wear. The break-in period is the time required to wear down these direct contact points, and this period is called the break-in period.
