Can a New Car Be Driven on the Highway During the Break-in Period?

[DiKayden]

New cars can be driven on the highway during the break-in period, but it is necessary to control the speed and engine RPM. Generally, the speed of a new car on the highway should not exceed 100 km/h, and the engine RPM should be kept below 3000. It is also advisable to avoid overloading during the break-in period. For new cars in the break-in phase, urban roads are relatively better as the complex conditions allow for thorough vehicle conditioning. Requirements for driving during the break-in period: 1. Maintain smooth starts, avoid sudden acceleration, and do not let the engine RPM get too high; 2. Before starting, ensure the coolant temperature reaches at least 50°C; 3. Shift gears promptly while driving—avoid prolonged use of a single gear, and do not drive at low speeds in high gears or vice versa; 4. Choose good road surfaces to prevent excessive vibration, impact, or emergency braking; 5. Use high-quality fuel and engine oil, and avoid using engine wear additives.
