What is the appropriate speed for running-in a sedan?
2 Answers
During the running-in period of a sedan, the speed generally should not exceed 80 kilometers per hour. Below are specific details about the running-in period: 1. Introduction: The running-in period refers to the initial driving distance after a new car leaves the factory, allowing the engine components to operate smoothly. The typical running-in mileage for a new car ranges from 1,000 to 3,000 kilometers. 2. Precautions during the running-in period: Avoid emergency braking, as it not only impacts the braking system that is in the running-in phase but also increases the shock load on the chassis and engine. It is best to avoid emergency braking within the first 300 kilometers of driving. Avoid overloading the vehicle. Avoid long-distance trips.
I remember that during the break-in period of a new car, not driving too fast is key. Generally, keeping the speed between 50 to 70 kilometers per hour is ideal, as this helps avoid excessive friction between internal engine components, which can lead to premature wear. Just like raising a car, it needs time to adapt gradually. Within the first 500 to 1,000 kilometers, avoid accelerating suddenly or taking long high-speed trips. It’s also important to avoid driving at a constant speed for too long, such as maintaining the same speed for an hour without variation, as this doesn’t allow the parts to break in properly. Occasionally changing speeds by gently pressing the accelerator is better. Personal experience has taught me that this approach extends the car’s lifespan and improves fuel efficiency later on. If you notice unusual noises while driving, it’s best to stop and check promptly to prevent minor issues from becoming major ones. In short, following the manual’s recommendations is the safest bet, as each car model might have slight differences.
