What are the tips for driving during the break-in period of a new car?

During the break-in period of a new car, it is advisable to shift to lower gears in advance to protect the engine. Here are some driving tips for the break-in period of a new car: 1. Before driving: After starting the engine, do not abruptly increase the RPM or continuously press the accelerator pedal aggressively. Avoid running the engine at constant high (or low) speeds; it is better to operate the engine at moderate RPM, generally not exceeding 80% of the maximum RPM. 2. While driving: Do not exceed the maximum speed for each gear; avoid prolonged high-speed driving or accelerating while in high gear. Driving speed should generally be controlled within 70% of the maximum speed for each gear. Avoid driving at a single speed for extended periods, whether fast or slow, and do not drive slowly while in high gear. 3. Other considerations: Shift gears promptly according to road conditions, taking into account the reduced engine power during the break-in period. Shift to lower gears in advance and avoid forcing the use of high gears to prevent excessive engine load. The load during the break-in period should not exceed 70% of the rated capacity, and towing trailers or other vehicles is not allowed. For passenger cars during the break-in period, the engine RPM should be controlled within 2500~4000 RPM, and the maximum speed should be kept below 90 km/h. Avoid emergency braking to prevent damage to mechanical components. Gentle use of the brakes can help with the break-in process and extend the lifespan of the braking system. To shorten the break-in time for the brakes as much as possible, during the first 200 km of driving, you can appropriately increase the number of brake applications to accelerate the break-in of the brakes. Fuel and oil selection during the break-in period: To prevent accelerated wear of components due to knocking during the break-in period, use high-quality gasoline with a higher octane rating. Since the internal components of the engine have smaller clearances during the break-in period, choose high-quality, low-viscosity oil to ensure good lubrication of the friction surfaces, and avoid using engine wear-resistant additives.

Let me, a veteran driver with 20 years of experience, share some insights about the break-in period. Don't rush to speed when you get a new car—components like the engine and transmission need time to adjust, just like new shoes. The first 1,000 kilometers are critical: keep the engine RPM below 3,000 and speed under 90 km/h. Press the accelerator as gently as stepping on an egg, anticipate road conditions to avoid sudden braking. A useful trick is to avoid maintaining a constant RPM for too long—slightly adjust your speed periodically on highways. Also, after a cold start, let the engine warm up for 30 seconds before driving slowly until the coolant reaches operating temperature. These details matter—proper break-in can significantly improve fuel efficiency later on.
