Is it necessary to break in a new automatic transmission car at high speed?

[DeIsabela]

New cars do not need to be broken in at high speed. Users should not operate the car under high-speed and high-load conditions when using a new car, as this can be harmful to the engine. The best way to break in a new car is to drive it under normal working conditions, and new cars do not have carbon deposits. Below are some taboos regarding the break-in period of a new car: Avoid emergency braking, as it not only impacts the braking system during the break-in period but also increases the load on the chassis and engine. It is best not to perform emergency braking within the first 300 kilometers of driving. Avoid overloading. If a new car is operated at full load during the break-in period, it can cause damage to the components. Therefore, within the first 1,000 kilometers of driving, the load should generally not exceed 75% to 80% of the rated capacity.
