Let your car enter a good operating state
For the new car

Pulling high speed is to speed up the car
Time to enter the best state
When pulling high speedHigh work speed of the engine
Mechanical wear the most

These oils with a large amount of debris are pulled high -speed
will increase the engine loss
Therefore, the recommendation isAfter replacing the oil for the first timePull high
The effect of reaching a high -speed running -in without exacerbating wear
It is recommended to drive at a speed of 100 to 120km/h when pulling the high speed
Don't open to 150km/h、200km/h or even speed to pull high speed
Since the new car has not yet entered the best state
Too high -speed even causes traffic risk
In short, my brother suggested that old drivers
Reasonable pull high speed after changing the first box of oil
