Today, we will talk about some wrong running-in methods for automobiles.

Error ①: During the running-in period, the engine speed should be controlled between 2000 and 3000 rpm, when the engine load is the lightest.

Don't drive violently during running-in, so as not to wear the car due to poor lubrication. However, when the new car is running in, as long as it does not exceed 60% of the speed before the red line. If it is an automatic car, you don't have to consider the speed, and everything can be handled by the gearbox itself.

Error ②: The running-in speed of new cars should be slower than faster, and should not exceed100 km/h/h. ..

In fact, there is no direct relationship between vehicle speed and engine speed. Controlling the vehicle speed has little effect on the engine, as long as the engine runs within a reasonable range. Know more and more about cars! No need to control the speed. However, it is really difficult to find a way beyond 100km/h unless you enter the expressway.

Mistake ③: Gear shifting is based on the vehicle speed, not the engine speed, so the speed of each gear should be adjusted to the best efficiency section.

In fact, each gear has a corresponding speed range. However, if you are in high gear, there is no need to consider controlling the speed. As long as the speed is matched, the high speed will upshift and the low speed will downshift.

Mistake 4: Don't do it too early. If you switch to ordinary engine oil too early, you will not get better results.

The engine oil used when the new car leaves the factory is not for you, but for you when you run in the car. But more and more car knowledge is known! Some manufacturers are not equipped with special running-in oil. Because the running-in oil is easier to consume, it can be replaced in advance.

Mistake ⑤: Never brake suddenly during the running-in period.

If there is an emergency during running-in, can you stop suddenly? Therefore, there is no need to pay too much attention to the brake system, but it is also necessary to pay attention to the fact that the brake pads cannot be braked frequently to avoid serious wear, and the brake pads should be replaced in advance.
