Is it necessary to drive a new car on the highway for a certain distance?

[VonEdward]

New cars do not need to be driven on the highway. The specific reasons are as follows: 1. During the break-in period, maintain the speed at two-thirds of the maximum speed. For example, if the maximum speed is 150, ensure it does not exceed 100 during the break-in period. 2. After the 5,000-kilometer break-in period, you can gradually increase the speed. Driving on the highway for a few minutes is sufficient because high speeds increase engine wear. Driving at high speeds during the break-in period will only cause damage and not help. After driving for three months or 3,000 kilometers, the break-in period is over, and the car needs maintenance. After maintenance, it is necessary to drive on the highway to activate the engine's power limit. This is considered high-speed running-in. Performing high-speed driving periodically is beneficial for the car.
