Does a car need a break-in period?

[AmirLee]

Automobile break-in period is not only the adaptation between the driver and the car, but also the running-in between various contacting and friction components of the vehicle. Due to advancements in modern automobile manufacturing processes, the break-in period for new cars has been significantly shortened. The break-in period for new cars has the following characteristics: 1. More driving malfunctions: Due to factors such as improper assembly of components, new cars tend to have more driving malfunctions during the break-in period; 2. Higher fuel consumption: To ensure that new cars operate under light load during the break-in period, carburetor-equipped cars are installed with speed limiters, which can easily cause excessively rich air-fuel mixture, thereby increasing fuel consumption; 3. Lubricating oil is prone to deterioration: During the break-in period, the rough surfaces of components and the small gaps between them can cause the temperature of the lubricating oil to rise.
