Is There a Break-in Period for a New Car?

[SanFrank]

New cars do have a break-in period. During this period, the following points should be noted: 1. Normal driving during the break-in period: Control the maximum speed to 100Km/h and drive 3000-5000 kilometers for the break-in. 2. New transmission components of the car: The surfaces of the components always have certain minor imperfections, which result in less tight fitting and meshing between the components during operation, causing more intense friction at the contact points. If the operating speed is too high, it may lead to permanent damage to the components due to excessive friction temperature or load at the contact points. 3. Changing the lubricating oil: During the initial operation of new car transmission components, the relative speed at the contact points should not be too high, and the lubricating oil should be changed in time to prevent metal debris suspended in the lubricating oil from entering the friction surface and accelerating component wear.
