Is it okay for a new car to run continuously for four hours?
2 Answers
During the break-in period of a new car, it can be driven continuously for 4 hours, but the engine speed should not exceed 2000 rpm, and the speed should not exceed 80 km/h. Break-in process: The break-in mileage for a car is 1000–2500 kilometers, while imported cars generally have a longer break-in period, mostly 1500–3000 kilometers. The break-in period is divided into three stages. The initial break-in occurs within the first 100 kilometers, the preliminary break-in is achieved by 200 kilometers, and an oxide film forms by 3000 kilometers. Driving speed: During the break-in period, it is best to drive at low speeds. Generally, the maximum speed for a loaded truck should not exceed 45 km/h, while for passenger cars, the top speed should remain within 50–80 km/h.
A new car can definitely run continuously for four hours. Vehicles undergo rigorous testing before leaving the factory and are designed with long-distance driving in mind. I've studied data on many car models, and modern engine cooling and lubrication systems are highly advanced, making overheating unlikely under normal usage. However, new cars have a break-in period, typically within the first 1,000 kilometers, where components are still adapting. It's advisable to vary speeds during this period to avoid prolonged high-speed cruising, as it may accelerate wear. Taking a break every two hours or so allows the engine to rest while also checking oil and coolant levels. The risk of fatigued driving is greater, so brief stops help both the driver relax and monitor the car's condition, ensuring safety and long-term vehicle health.
