What is the recommended speed during the car break-in period?

The recommended speed during the car break-in period is as follows: 1. Initial break-in period (1-500 km): The speed should not be too fast, generally below 70-80 km/h, and the engine speed should not exceed 2,200 rpm. 2. Mid-term break-in period (500-1,000 km): The maximum speed can be appropriately increased, generally reaching 90-100 km/h, with the engine speed still below 2,500 rpm. Increasing the speed moderately not only does not affect the engine but also promotes the break-in process and allows you to check for any abnormalities during acceleration. 3. Late break-in period (1,000-1,500 km): The speed can be increased to below 120 km/h. The break-in is a gradual process that must be carried out step by step. The engine speed should not exceed 3,000 rpm.
When I first bought my new car, I specifically asked the mechanic about speed control during the break-in period. He said that the internal components of a new engine need to gradually adapt, and it's best to maintain a speed between 60 to 80 km/h, not exceeding 100 km/h, as higher speeds can increase mechanical wear and lead to more future malfunctions. The first 1,000 kilometers are particularly critical—avoid prolonged high-speed driving, sudden acceleration, or slamming the throttle, and try to keep the RPM between 2,500 and 3,000 for smoother driving. During regular driving, varying your speed helps the components break in better. For example, with the car I drove before, after the break-in period, fuel consumption noticeably decreased, the engine ran smoother, safety improved, and maintenance costs were reduced. Regularly checking tire pressure and engine oil is also crucial for long-term vehicle durability.
When I first got my new car, I was excited but also cautious. The 4S store staff reminded me not to drive too fast during the break-in period, suggesting a speed range of roughly 80 to 100 km/h and avoiding constant high-speed cruising. The principle is that the piston rings and cylinders of a new engine need to gradually conform to each other. Excessive speed or a constant driving rhythm can increase friction and affect the engine's lifespan. Keeping the RPM under 3,000 is advisable, along with avoiding sudden braking, especially within the first 500 kilometers. I noticed that driving habits have a significant impact—gradual acceleration and smooth deceleration help protect the engine, reduce the risk of oil burning, and ensure more stable vehicle performance. After the break-in period, the car responds more quickly, fuel efficiency improves, and long-distance driving becomes more worry-free. Don’t overlook regular maintenance, and consider changing the engine oil a bit more frequently.
