How Many Kilometers for the Break-in Period?

The break-in mileage for a new car is 1000 kilometers to 3000 kilometers. Here are some precautions during the break-in period: 1. 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, then start the engine. This is because the fuel pump begins working as soon as the ignition is turned on, adjusting oil pressure and fuel injection volume. Therefore, waiting a few seconds before starting helps protect the new car's engine. 2. 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 is best to avoid emergency braking within the first 300 kilometers of driving. 3. Avoid overloading: If a new car is driven at full load during the break-in period, it can cause damage to the mechanical components. Therefore, within the first 1000 kilometers of driving, domestic cars should not exceed 75%-80% of the rated load, and imported cars should not exceed 90% of the rated load.
I've driven several new cars before, and the break-in period is usually between 1,000 to 1,500 kilometers, depending on the owner's manual. My old car didn't stabilize in performance until after 1,500 kilometers. For the first few months, avoid long-distance trips or aggressive acceleration. Maintain a moderate speed and keep the RPM below 3,000 to ensure even wear of engine components. I've heard some people neglect the break-in period, resulting in faster engine wear and higher repair costs later. I recommend checking the engine oil and coolant after each drive to ensure there are no leaks. If driving on the highway, keeping it under 100 km/h is the safest. After completing the break-in period, a full maintenance check will help the car run smoother. Be extra cautious during the first few hundred kilometers—avoid heavy loads or steep climbs to let the car gradually adapt to road conditions.
Common issues with new car break-in during repairs, the standard is 1,000 to 1,500 kilometers, depending on the engine type. I always remind friends not to speed during this period, otherwise, parts will experience excessive friction and have a shorter lifespan. The key is not to accelerate immediately during cold starts; wait until the water temperature is normal before driving. Gears and bearings need a slow break-in, and it's better not to exceed 90 km/h at high speeds. Checking the manual is the golden standard; some modern cars, like diesel engines, may require over 1,500 kilometers. I also advise owners to check tire pressure before each trip to avoid accidents. Changing the oil after the break-in is particularly important—don't wait too long for maintenance, as it can save on major repair costs.
