What is the recommended speed for breaking in a new car?

[VanFelix]

The recommended speed for breaking in a new car is between 50 to 90 kilometers per hour. Precautions during the break-in period include: 1. Warm up the engine before starting; 2. Avoid emergency braking; 3. Prevent overloading; 4. Avoid long-distance driving; 5. Do not drive at high speeds; 6. Use high-quality gasoline; 7. Do not remove the speed limiter prematurely; 8. Shift gears in a timely manner; 9. Properly adjust the ignition and fuel supply systems. Methods for the break-in period are: 1. Preheat the cold engine—proper warming up ensures better lubrication of engine oil inside the engine, reducing wear; 2. Shift gears promptly while driving, especially for manual transmission cars—reasonable gear shifting during the break-in period avoids high gear with low RPM or low gear with high RPM; 3. Perform timely maintenance on the new car during the break-in period.
