What is the appropriate speed for breaking in a new car?

[SanDeclan]

During the break-in period of a new car, the speed should generally be maintained between 50-90km/h. Here are some precautions to note during the break-in period: Avoid high-speed driving: Try not to let the car's speed reach 120km/h, as this helps maintain the engine's performance and prolong its lifespan. Avoid overloading: Placing excessively heavy objects in the car during the break-in period undoubtedly puts stress on the vehicle. Overloading often requires frequent gear changes, and the constant shifting between high and low gears can be very detrimental to the engine. Avoid driving on extremely poor road conditions: Driving on very rough roads during the break-in period can cause significant tire wear. Moreover, prolonged driving under such conditions with the engine constantly operating at high power can inevitably lead to damage.
