Can a car run on the highway during the break-in period?

Nowadays, new cars do not need to run on the highway during the break-in period. Here is some relevant knowledge about the car break-in period: 1. The reason for the break-in period: In the past, due to backward automotive production technology, the dimensions of car parts were not precise and were relatively rough, which resulted in the transmission and engine not being able to mesh and operate perfectly after installation and debugging. Therefore, the concept of the break-in period was introduced. 2. The concept of the break-in period: The break-in period generally refers to the process of contact, friction, and meshing of mechanical parts during initial operation. Nowadays, it is often used to describe the period of mutual familiarization and adaptation between two things or within an organization.

When I first bought my car, I also wondered about this—whether a new car in the break-in period could be driven on the highway. I remember in the first month, I treated that new car like a treasure and followed a lot of advice from experienced drivers. They said the engine was fresh from the factory, with tiny burrs between parts that needed gentle driving to smooth out. High RPMs on the highway could easily cause engine overheating and accelerated internal wear, affecting the car's lifespan. I obediently drove 1,000 kilometers in the city before daring to hit the highway, and later, the car's fuel efficiency and smoothness felt great. Of course, with today's advanced manufacturing technology, the owner's manual says moderate highway driving is fine, but it recommends avoiding sudden acceleration and prolonged speeds over 120 km/h in the early stages. After all, the break-in period is about laying a solid foundation—repairs can be expensive if issues arise. In short, be patient, prioritize safety, and getting a thorough check-up at the end of the break-in period will give you extra peace of mind.

When it comes to driving on highways during the break-in period, I think it varies by car. As someone who enjoys tinkering with cars and has read many repair manuals, I've noticed that modern engine materials and lubrication systems have improved, making them less delicate than older models. It's perfectly fine to drive on highways during the break-in period, as long as you keep the RPM below 3,000. Manufacturers typically recommend gentle driving for the first 500-1,000 kilometers, after which highway cruising can actually benefit the break-in process—engines wear components more evenly at constant speeds. My own experience was taking a highway trip two weeks after buying a new car, maintaining a speed of around 100 km/h, with no issues. However, it's important to avoid racing, hard braking, or sudden acceleration, as these can increase wear risks. Additionally, after a cold start in winter, it's essential to wait for the oil temperature to rise before accelerating. Overall, as long as you drive gently, the break-in period shouldn’t prohibit highway driving.

Breaking-in period on highways? I drove my first car on the highway during the break-in period and ended up regretting it. For the first 2,000 kilometers of a new car, it's best to take it easy because the engine and transmission components are still adapting to each other. High-speed operation generates increased friction and heat, which may accelerate wear. On that long-distance trip where I drove over 120 km/h, the technician later found slight scratches on the piston rings during maintenance and recommended keeping speeds between 80-100 km/h initially, avoiding sudden throttle inputs. I've learned my lesson now – during the break-in period of a new car, I stick to city and short-to-medium distance driving, only attempting highways after the odometer shows over 1,000 km. Simply put, patience brings peace of mind.
