Brush car weather

There is also a lot of knowledge about car maintenance.

With the development of national strength, this level has been continuously improved, and the quality of life of the broad masses of people has also been greatly improved. The increase in car ownership has also made more and more people experience the convenience of travel. Now is the Qingming small holiday, and many people will choose to travel and relax at this time.

However, you must remember to maintain your car regularly. Now many car owners have noticed the importance of maintenance for your car, but you often make some mistakes in maintenance. Few people know these secrets about parts replacement, and the maintenance staff will not tell you. Let's talk about these minefields today so that you can avoid them effectively.

First, brush the car under bright light on sunny days.

I believe many people will choose to brush their cars when the weather is good. Many people think that it is sunny and the temperature is quite good at this time, which can facilitate the rapid drying after brushing the car.

In fact, this idea is wrong. In this weather, because of the convex lens, the top of the car paint will produce a relatively high temperature. After a long time, not only the car paint will be damaged, but even the engine will age prematurely. In fact, waxing at this time does not have much effect, but it will make the body color uneven.

Second, the tighter the screw, the better.

In our car, there are many small parts such as screws and nuts, and many people will let the repairman tighten them when repairing the car.

This practice is also wrong, and it needs to be tightened, but it must not be tightened too tightly, because at this time, the screw is deformed because of the thermal expansion and cold contraction of the metal, and the tightness of each part is different.

All brands of engine oil are mixed.

Many people prefer the new to the old. They seldom use a brand for a long time. After a long time, many people will choose to welcome other brands.

However, oil is not like this. This is because although the viscosity of different brands of engine oil is not much different, the composition of different brands of engine oil is different. If used together, a certain chemical reaction may occur, and the consequences are unimaginable.

Fourth, the higher the gasoline label, the better.

I believe many car owners prefer to use high-grade gasoline. However, the higher the grade of gasoline, the better. Even many high-end cars don't need to upgrade their gasoline. At present, the grade of gasoline on the market basically refers to their octane number, which means that the antiknock performance of gasoline does not have much image in other aspects.
