The old driver talked about how to run in the new car.

1 and 500 km are the initial running-in. At this time, the speed should not be too fast, generally below 70-80 kilometers, and the speed should not exceed 2200.

2. 500- 1000 km is the medium-term running-in, and the maximum speed can be increased appropriately, generally reaching 90- 100 km, and the speed is still below 2500 rpm. Properly increasing the speed not only affects the engine, but also promotes the running-in. If you increase the speed, you can see whether there is any abnormality.

3. 1000- 1500 km is the later running-in, and the speed can be reduced below 120 km. Because running-in is a step-by-step process, we must gradually overweight. The rotating speed should not exceed 3000 rpm.

4. When all cars are driving at low speed, the actual burden is greater than that of driving at medium speed, so the running-in period should not be less than 60 km/h for a long time. The speed must be gradually increased. At the same time, if you keep running at 80km/h after the running-in period and suddenly increase the speed, the new car will not adapt, so you should gradually increase the maximum speed during the running-in period.

5. Don't drive at a constant speed for a long time during the running-in period, but have variable speed.

6. When driving in the running-in period, avoid sudden braking and sudden speed increase.
