What is the suitable speed for breaking in a new car?
2 Answers
New cars should be driven at 70-80 km/h during the break-in period. Here are specific precautions for breaking in a car: Avoid overloading: The load capacity of a car during the break-in period should not exceed 75% of the rated load. Overloading will increase the burden on components such as the engine, transmission, drivetrain, and suspension system, accelerating wear. Break-in road conditions: Choose relatively flat driving surfaces to avoid vibration, impact, or emergency braking. Gasoline: The gasoline used during the break-in period of a new car should not be of a lower grade than that specified by the manufacturer. Proper operation: Correctly adjust the ignition system and fuel supply system.
Recalling the break-in experience of my first new car, I was really excited when I bought it but knew I had to be careful. The manual recommended keeping the speed below 90 km/h for the first 500 to 1000 kilometers. I usually kept it around 60 in the city and under 100 on the highway. A friend who is a mechanic reminded me that the engine piston rings are rough when new, and high speeds and RPMs can cause overheating and wear, increasing fuel consumption and noise. So I made sure to accelerate and brake smoothly, avoided long trips, and let the parts gradually adapt. Later, the car ran over 100,000 kilometers with very few issues, proving that managing speed during the break-in period was worth the long-term benefits.
