When is the best time to take a new car for high-speed driving?

[OEliza]

It is best to take a new car for high-speed driving after its first maintenance. Relevant details are as follows: 1. Purpose of high-speed driving: Avoid 'high-speed driving' before the first maintenance of a new car, as it can cause severe engine wear. High-speed driving for a new car is only intended to remove carbon deposits from the engine. During the break-in period, prolonged slow driving of a new car can easily lead to carbon buildup in the engine (high-speed driving should be done some time after the first maintenance). This applies not only to new cars but also to cars frequently driven in congested areas. If there is no time or opportunity for high-speed driving, you can drive at 'high engine speeds' on city roads to reduce carbon deposit formation. 2. Significance of high-speed driving: The real purpose of high-speed driving is to increase the engine speed, which should be maintained between 3000 and 5000 RPM. In the end, 'high-speed driving' is only meant to reduce carbon deposits in the engine, not to break in the various components of the car, so new car owners should pay special attention to this.
