Do modern cars still require a break-in period?

[MacGenesis]

Modern cars still require a break-in period. Here is more information about the car break-in period: 1. Mileage for the break-in period: Generally, it is 1000 to 3000 kilometers. During this period, the owner should reasonably control the speed and avoid sudden braking or acceleration. 2. Preheating before starting: This ensures proper lubrication of the engine and prevents unnecessary faults during the break-in period, which could affect normal usage. 3. Speed control: The engine break-in period requires approximately 1000 kilometers. For the first 500 kilometers, it is recommended to drive at speeds between 60 to 70 km/h, keeping the RPM below 2200. Between 500 to 1000 kilometers, the speed can be increased to 90 to 100 km/h, with the RPM below 2500, to facilitate the break-in process.
