What is the recommended running-in speed for a vehicle?

[OBethany]

Vehicle running-in speed is generally most suitable between 50 km/h to 90 km/h. The running-in period for a car refers to the initial driving phase of a new vehicle or after major repairs, typically covering 1,000 to 1,500 kilometers. This mileage ensures full contact, friction, adaptation, and stabilization of mechanical components. During this period, the vehicle's parts can adjust and enhance their environmental adaptability while wearing down surface irregularities on components. For the first 500 kilometers, it's advisable to maintain speeds between 60-70 km/h with engine revolutions preferably not exceeding 2,200 rpm. Between 500-1,000 kilometers, the speed can be increased to 90-100 km/h while keeping revolutions below 2,500 rpm, which facilitates proper running-in.
