What speed should be maintained during the car break-in period?
2 Answers
1-500 kilometers, maintain a speed of 70-80 km/h; 500-1000 kilometers, maintain a speed of 90-100 km/h; 1000-1500 kilometers, keep the speed below 120 km/h. Here is more information about the break-in period: 1. Brief description: The car break-in period refers to the initial driving stage of a new car or after a major overhaul, usually 1000~1500 kilometers. This is the basic mileage to ensure that the components fully contact, friction, adapt, and shape. 2. Precautions: Avoid sudden acceleration or deceleration, do not let the engine speed get too high in a new car, do not start the car cold in winter without warming it up, avoid accelerating in high gear with low RPM for manual transmissions, do not brake hard or frequently, and avoid overloading.
When I bought my new car, I paid special attention to how to drive during the break-in period. I remember the sales guy said the first 1,500 kilometers are the most critical, and the RPM shouldn’t exceed 4,000. On the highway, I kept it under 100 km/h, and in the city, I drove normally, slowing down when needed. It’s not just about speed—avoiding sudden acceleration and hard braking is also important. Don’t rev the engine hard when going uphill, and don’t coast in neutral on long downhill slopes. After all, the parts of a new car are still adapting to each other. Driving gently helps the engine, transmission, and other components break in smoothly, which benefits fuel efficiency and performance in the long run. I stuck to this approach, and now, after 50,000 kilometers, my car is still in great shape.
