It is acceptable for a brand new car to undertake long-distance highway driving immediately after purchase. However, there are several precautions to consider when driving a new car at high speeds: Inadequate or Excessive Load: When driving at high speeds, the new car must be in a fully loaded state. Otherwise, the effort will be in vain. Therefore, ensure the vehicle is loaded according to the manufacturer's specified maximum capacity. If there are not enough passengers, items can be placed in the trunk to achieve the required weight. Driving Before the First Maintenance: High-speed driving should only be performed after the first maintenance service. This is because the first maintenance includes checking and tightening all bolts, as well as inspecting various fluid levels, ensuring the car is safe to drive at high speeds. High-Speed Driving Before Oil Change: High-speed driving requires not only skill but also proper timing. The quality of the engine oil is a critical factor affecting the engine. Therefore, avoid high-speed driving before an oil change. During high-speed driving, the engine operates at high RPMs, leading to maximum mechanical wear. The initial batch of oil contains the most metal shavings and impurities. Using this contaminated oil for high-speed driving can significantly increase engine wear and even cause abnormal damage. As a result, the car will not be in optimal condition after the break-in period.

I'm a new car owner who just picked up the vehicle and was also conflicted about this. The salesperson said there's no issue with taking a new car on the highway, as modern car designs have improved, but it's best to break it in for the first 500 kilometers—avoid rapid acceleration and speeding. The manual states that initially installed engine components need time to adapt, and maintaining a steady speed of 100 km/h is smoother than stop-and-go city driving, also helping to reduce carbon buildup. Personally, I took my car on the highway on the third day to drive back to my hometown, covering over 200 kilometers at 90-100 km/h without any issues. I recommend new owners try this approach—don’t worry about the tires or engine, just avoid slamming the accelerator or braking hard. Check the tire pressure and coolant for safety. Proper break-in ensures the car is more durable and fuel-efficient later, saving money and giving peace of mind.

I've been driving for ten years and have changed three new cars. My experience is that it's completely feasible to drive a new car on the highway. During the break-in period, which is about 500 kilometers, driving at a steady speed on the highway is actually beneficial, as it avoids hard engine break-in. For example, my previous car was driven on the highway within the first 300 kilometers, maintaining a speed of 80-95 km/h, which was much more worry-free than city traffic jams. This allows the metal parts to fit together smoothly and extends their lifespan. Avoid letting the RPM get too high, as it can easily overheat and damage the oil seals. Before long trips, check the manual to avoid overloading or speeding, ensuring a safe and fuel-efficient journey home. In short, as an experienced driver advises, practicing more on the highway with a new car is fine, just take it easy.

As a car enthusiast, I often delve into engine structures. New cars can handle highways right off the lot, and with modern engine materials being more advanced, the break-in period requirements have lessened. It's recommended to drive gently for the first 1,000 kilometers. Maintaining a steady speed on the highway is better than frequent stops and starts, as it helps evenly smooth out rough surfaces on components and reduces wear. Keep your speed between 80-100 km/h, avoiding high RPMs or sudden braking. Highway driving also helps blow away initial dust accumulation. Ensure tire pressure is correct and the cooling system operates smoothly. Don’t let your guard down on safety.
