How many kilometers does a new car need to break in?

[DelHayden]

New car break-in period is generally between 1,000-1,500 kilometers. Although modern car engines undergo cold running-in treatment before leaving the factory, the more important purpose of the break-in period is to develop good driving habits. Relevant information is as follows: 1. Break-in period: In the early stage (below 500 km), speed should be maintained at 60-70 km/h, with engine RPM not exceeding 2,200 for optimal performance. 2. Mid-stage: When reaching 500-1,000 km, speed can be increased to 90-100 km/h with RPM below 2,500. This promotes proper break-in. 3. Final stage: After reaching about 1,500 km, speed can be increased to below 120 km/h. The break-in process should be gradual, with RPM never exceeding 3,000.
