How Long Does a New Car Need to Break In?

The break-in period is generally about 500 kilometers of driving. Here are some precautions to take during the break-in period: 1. Avoid emergency braking: Emergency braking not only shocks the braking system during break-in 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. 2. Avoid overloading: Running a new car at full capacity during the break-in period can damage the components. Therefore, within the first 1,000 kilometers of driving, the load should generally not exceed 5%-80% of the rated capacity. 3. Avoid long-distance trips: Long-distance trips during the break-in period increase the continuous working time of the engine, which can easily cause wear on the components. 4. Avoid changing the oil too early: The initial oil in a car is specifically designed for the break-in period, with low viscosity, excellent heat dissipation, cleaning, and oxidation resistance properties. Some oils even include grinding agents that aid in the break-in process. Therefore, during the break-in period, change the oil only according to the manufacturer's specified time and not too early. 5. Avoid starting without warming up: A new car must be warmed up before starting. Warming up essentially gives the engine sufficient lubrication time, especially for turbocharged models, which need to be warmed up before starting.
When I first picked up the car, the 4S dealership mentioned that the break-in period is generally around 1,000 kilometers. This allows the internal engine components like pistons, rings, and gears to gradually wear in smoothly. For the first few hundred kilometers, drive gently, avoid sudden acceleration or high RPMs, and try not to exceed 3,000 RPM. Prolonged high-load driving can increase wear and affect the engine's lifespan. Additionally, remember to monitor tire pressure and change the oil regularly, as this helps the entire system run more healthily. After this phase, you'll notice the car becomes more fuel-efficient and the power delivery smoother. I recommend checking the user manual for specific mileage requirements, as they vary by brand. In short, taking the time to drive carefully will reward you with a longer-lasting car and better performance.
Car technology has advanced so much nowadays that lengthy break-in periods are no longer necessary like before. After checking the user manual, I found many new cars have their engines partially tested at the factory, with the break-in period possibly just 500 to 1000 kilometers. For the first few days of driving, it's best to avoid high-speed bursts on highways—keeping it under 60 km/h is sufficient. The key is to allow mechanical components to transition smoothly, reducing friction damage. If you're in a hurry to use the car, don't worry too much; modern designs are well-engineered to adapt to minor issues automatically. Also, pay attention to even tire wear and brake sensitivity—these details can enhance your driving experience. Just take it easy and don't stress yourself out.
