Can a New Car Be Driven on the Highway During the Break-in Period?
2 Answers
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.
I've been driving for decades, and it's completely fine to take a new car on the highway during the break-in period. Thinking back to my first two new cars, I drove them straight home on the highway after picking them up. Just don't keep the gas pedal floored all the time. The break-in period is usually the first 1,000-2,000 kilometers, and the key is to let the engine components gradually adapt—avoid revving too high or speeding. On the highway, I suggest occasionally varying your speed, like driving at 70 km/h for ten minutes, then accelerating to 80 km/h before slowing back down. Don't maintain a constant speed for too long, as this helps the pistons and cylinder walls wear in more evenly. Remember to check the oil dipstick and tire pressure when parked to ensure everything is normal. Highway driving won't cause issues, but treat the car gently to ensure it lasts longer.
