What is the most suitable speed for a new car during the break-in period?
2 Answers
During the break-in period, the recommended speed for a car is between 70 to 80 kilometers per hour, with a break-in mileage of approximately 500 kilometers. The break-in period is a fundamental process to ensure that mechanical components fully contact, friction, adapt, and stabilize. During this period, the car's parts can adjust and enhance their ability to adapt to the environment, wearing down any protrusions on the components. Precautions to take when using a car during the break-in period include: 1. Preheating before starting; 2. Avoiding emergency braking; 3. Preventing excessive load; 4. Avoiding long-distance trips; 5. Not driving at high speeds; 6. Using high-quality gasoline; 7. Not removing the speed limiter prematurely; 8. Shifting gears in a timely manner; 9. Correctly adjusting the ignition and fuel supply systems.
I remember being particularly cautious about the break-in period when I first drove my new car. The break-in period is essentially about allowing the car's components to adapt and wear in together, so it's best not to push it too hard. I usually keep my speed between 60 to 90 km/h, and even on highways, I don’t exceed 100 km/h. Most importantly, avoid straining the engine—for manual transmissions, it’s best not to exceed 3,000 RPM. Some experienced drivers online suggest that the first 500 kilometers are especially critical, requiring gentle handling like caring for a newborn. Oh, and occasionally driving on slight inclines to let the engine work under moderate load is actually beneficial. For daily commuting, this approach is more than enough and even helps save fuel.
