How long after buying a new car can it be driven on the highway?

A new car can be driven on the highway immediately. Nowadays, the engine RPM of properly tuned cars is generally not very high. The speed limit on highways is usually up to 120 km/h, with RPM typically not exceeding 3500, so driving on the highway poses no problem for the car. However, for the driver, it might be different. Even experienced drivers need some time to adapt to a new car. Always prioritize safety based on the actual situation. Here are some precautions for highway driving: 1. Drive at both low and high RPMs, shifting gears only when the engine exceeds 3000 RPM. 2. For automatic transmission cars, you can switch to "manual mode" or use lower gears to adjust. 3. Keep the engine RPM between 3000-5000.
You can take a new car on the highway right after purchase, but the engine has a break-in period. I often recommend avoiding frequent highway driving or rapid acceleration for the first 500 to 1,000 kilometers, as it can easily wear internal components. While cruising at a steady speed on the highway is fine, rapid acceleration may cause uneven engine heating, which over time could affect performance or fuel efficiency. Drive in the city for about a week first to allow components like the oil pump and bearings to break in properly. Avoid aggressive overtaking or heavy loads before the first oil change. A proper break-in can extend the engine's lifespan by 5-10 years, saving money and ensuring safety. On the highway, pay attention to tire pressure and coolant levels. New drivers should maintain a steady pace and avoid rushing.
