Is it necessary to drive a new car on the highway for a certain distance?

New cars do not need to be driven on the highway. The specific reasons are as follows: 1. During the break-in period, maintain the speed at two-thirds of the maximum speed. For example, if the maximum speed is 150, ensure it does not exceed 100 during the break-in period. 2. After the 5,000-kilometer break-in period, you can gradually increase the speed. Driving on the highway for a few minutes is sufficient because high speeds increase engine wear. Driving at high speeds during the break-in period will only cause damage and not help. After driving for three months or 3,000 kilometers, the break-in period is over, and the car needs maintenance. After maintenance, it is necessary to drive on the highway to activate the engine's power limit. This is considered high-speed running-in. Performing high-speed driving periodically is beneficial for the car.
To be honest, I've driven for over a decade and repaired many engines, but modern cars really don't need special highway runs for break-in. Older engines required gradual seating of piston rings and components, but today's vehicles undergo precision factory testing with pre-conditioned engine blocks and gears. Just follow your owner's manual – typically avoid hard acceleration/braking during the first 500-1,000km and prevent sustained high RPMs or prolonged highway speeds. Highway driving itself isn't wrong (it heats the engine to clear carbon deposits), but it's not mandatory for break-in. The key is varied driving initially – occasional highway trips mixed with city driving helps sensors adapt. Safety first: never risk speeding for break-in. Drive steadily, change oil on schedule, and your engine will last longer with fewer issues.
When I first bought my car as a novice owner, I also hesitated. I searched online and asked friends, and most said that modern cars don't require special highway runs since the engine is factory-tuned. The manual advises driving steadily for the first 1,000 kilometers, avoiding sudden acceleration or hard braking. Driving on the highway can test engine performance, such as running it at high speeds to clear carbon deposits, but it's not mandatory. I believe initial driving habits are more important—varying speed types, driving in suburban areas before hitting the highway, and taking it slow to minimize risks. Remember to schedule regular maintenance and check the engine oil. Safety comes first during the break-in period, and the engine will adapt well. Don't worry too much about old-school notions—driving as instructed ensures an economical and durable car.
As an auto enthusiast, I always delve into the details. Modern new cars with advanced engines don't require specific break-in procedures - highway driving is optional. The key during initial operation is gentle driving with varied speeds, avoiding prolonged operation at fixed RPMs to help components settle smoothly. While highway driving can heat up the engine under high load and clean carbon deposits, it's not essential. During the first 1,500km break-in period, steady driving helps oil films form and allows sensors to learn and adapt.
