How Long Should a New Car Be Broken In?

[PeytonLee]

The break-in period for a car refers to the initial driving phase after purchasing a new car or completing a major overhaul, typically covering 1,000 to 1,500 kilometers. This mileage is essential to ensure that mechanical components fully contact, frictionally adapt, and settle into their final form. Below are specific precautions to observe during the break-in period: 1. Avoid emergency braking: During the break-in period, try to avoid emergency braking as much as possible. Emergency braking not only impacts the braking system during break-in but also increases the shock load on the chassis and engine. 2. Avoid overloading: Running a new car at full load during the break-in period can cause damage to its components. To reduce the load on the body and powertrain, choose relatively flat road surfaces to avoid vibration, collision, or emergency braking.
