Should a new car be driven at high speeds after purchase?
2 Answers
It is recommended to drive a new car at high speeds after the first maintenance. Driving at high speeds can help remove carbon deposits from the engine, and gradually increasing the speed is beneficial for the engine. However, suddenly increasing the speed should be avoided as it may cause the new car to malfunction and damage the engine. Relevant information is as follows: 1. It is not advisable to drive at high speeds before the first maintenance: It is not recommended to drive at high speeds or "break in" the car before the first maintenance because the new car is still in the break-in period. During this period, the speed should be increased gradually, and sudden increases in speed should be avoided to prevent damage to the engine. 2. The reason for driving a new car at high speeds: The purpose of driving a new car at high speeds is to increase the engine RPM, not just to accelerate by pressing the throttle hard. A new car should not always be driven at low speeds during the break-in period, as this can lead to more carbon deposits in the engine. Whether it is a new or old car, "driving at high speeds" helps reduce carbon deposits in the engine. If it is not possible to drive on highways, driving at high RPMs on regular roads can also effectively reduce carbon deposits.
I've been driving for decades and there's no need to deliberately run a new car at high speeds for break-in. Modern engines are manufactured with high precision, and components like piston rings and cylinder walls are already pre-polished during production. Forcing high speeds only increases frictional heat, causing premature wear, damaging the engine, and wasting fuel. The correct approach is to drive gently for the first 1,000 kilometers, keeping speeds between 60-90 km/h, and frequently varying gears or speeds to help distribute oil evenly. Mix city and suburban driving, keeping RPMs below half of the redline. This protects the new car, extends its lifespan, and reduces pollutant emissions. Why bother with outdated ideas?
