What is the typical break-in mileage for a new car?

The break-in mileage for a car is generally between 1,000 to 2,500 kilometers. The specific mileage varies depending on the vehicle, and it's best to follow the manufacturer's guidelines to determine the break-in period for a new car. Typically, the break-in period for a new car refers to the initial driving phase after the car leaves the factory, during which the engine components are allowed to wear in smoothly. The break-in mileage is usually between 1,000 to 2,500 kilometers. Precautions for using a new car during the break-in period: Warm up before starting: This applies to fuel-injected cars. Before starting, turn the key to the second position and wait for 5-10 seconds before ignition. This is because the fuel pump begins working as soon as the ignition is turned on, adjusting fuel pressure and injection volume. Waiting a few seconds before starting helps protect the new engine. Avoid emergency braking: Emergency braking not only shocks the braking system during the break-in period but also increases the impact load on the chassis and engine. It's best to avoid emergency braking within the first 300 kilometers of driving. Avoid overloading: Running a new car at full load during the break-in period can damage components. Therefore, within the first 1,000 kilometers, domestic cars should not exceed 75%-80% of the rated load, and imported cars should not exceed 90% of the rated load. Additionally, to reduce stress on the body and powertrain, choose relatively flat roads and avoid vibrations, collisions, or emergency braking. Avoid long-distance trips: Taking a new car on long trips during the break-in period increases the continuous operation time of the engine, which can lead to excessive component wear. Use high-quality gasoline: The gasoline used during the break-in period should not be of a lower grade than specified by the manufacturer. Always use high-quality gasoline and avoid adding anti-wear additives, as this may result in insufficient break-in despite reaching the required mileage. Properly adjust the ignition and fuel systems: This helps address changes caused by installing a speed limiter and improves fuel efficiency during the break-in period.
The break-in period for a new car is generally between 1,500 to 2,000 kilometers, which is the standard range I've summarized from experience and is also commonly stated in the manual. The break-in process mainly allows the internal engine components to adapt to each other, reducing early wear. My old car developed noise issues after just a year due to improper break-in, and repairs were quite troublesome. Drive gently during this period—for the first 500 kilometers, it's best to stick to low-speed city driving, avoiding sudden acceleration or prolonged high RPMs, then gradually increase speed afterward. Modern car manufacturing has improved, and some models claim no special break-in is needed, but I believe safety comes first, as it can extend engine life. After the break-in, remember to visit the shop for an oil change to flush out any metal particles and check tire pressure and coolant levels—these small details help the car run longer and more fuel-efficiently. In short, each car model may vary, so it's best to check the manual for specific numbers.
