How many kilometers is the running-in period of the new car, and can it reach the best condition?
Some car maintenance manuals will mention the running-in of vehicles, but the details will be put in the user manual, such as Volkswagen Jetta. The manual points out that 1500 km is the running-in period, which requires that the throttle should not be fully opened and the speed should not exceed 5300 rpm. Don't shift gears at an inappropriate speed! Pay attention to check tire pressure, coolant and brake oil. For the vehicle speed, do not exceed 2/3 of the maximum speed, and the engine speed should not exceed 3000-3500 (different car companies have different requirements for engine speed).
When the mileage reaches about 500- 1000 km, it is the middle of the running-in period, and the speed is increased from 60-70 to 90-1000 km, and the optimal speed is below 2500 rpm. This can promote running-in. This car is not as fragile as we thought. Running-in came out in the eighties and nineties. There are hundreds of car parts. At that time, the machining accuracy of the mating surface of the parts was not high, so it was necessary to polish and seal the surface of the parts with precise mating.
This is the requirement of a car manual for running-in of vehicles, and it is also an understatement! Running-in mileage must reach 65,438+0,500 kilometers, but the speed requirement during running-in is relatively broad. As long as the running-in speed does not exceed 3/4 of the maximum speed, the first 500 kilometers is the initial running-in period. During this period, don't drive too fast, don't rotate too fast, keep the maximum speed below 80 km/h, and generally run for thousands of kilometers (not more than 60 kilometers) at a low speed, and you can work at full load after you are familiar with the car conditions.
