How many kilometers is the break-in period for a vehicle?

[Mildred]

New cars typically have a break-in period of 1,000 to 3,000 kilometers. The break-in period for new vehicles has the following characteristics: 1. More driving issues: Due to factors such as improper assembly of components, new cars tend to experience more driving problems during the break-in period. 2. Higher fuel consumption: To ensure the new car operates under light load during the break-in period, carburetor-equipped vehicles are fitted with speed limiters, which can easily lead to an overly rich air-fuel mixture, thereby increasing fuel consumption. 3. Engine oil degrades more easily: During the break-in period, the rough surfaces of components and the small gaps between them can cause the engine oil temperature to rise. Additionally, many metal shavings are worn off and mix into the oil, accelerating oxidation and degradation of the lubricant.
