Misunderstandings in car-loving DIY car maintenance

1. Misconception one: If the air conditioner is not cool, it must be fluorine-loving This is a common sense error, which is reasonable in special cases, but it is still undesirable in most cases.

2. Many drivers know that too low tire pressure is easy to cause tire wear, but if the tire pressure is too high, the car is prone to flat tires, which is more dangerous! Some drivers like to fill the tire pressure higher, thinking that this can be both overloaded and fuel-saving. However, if the tire pressure is too high, the tire will be less connected to the ground, the wear will be aggravated, and it is also easy to puncture the tire.

3. Misconception: The more oil, the better. If there is too much oil, the crankshaft shank and connecting rod will cause violent stirring when the engine is working, which not only increases the internal power loss of the engine, but also causes oil burnout failure due to the increase of oil splashed on the cylinder wall. Therefore, the amount of oil should be controlled between the upper and lower lines of the oil dicator.

5. Use special car cleaning liquid. When some people wash cars at home, they will use some cleaning liquids, such as laundry detergent, detergent, etc. to wash the car. In fact, it is not right to do so.

6. Pay attention to the order of car washing. The correct order should be the roof, front and rear covers, side of the body, lamps, bumpers, skirts and wheels.
