Do you know what's wrong with car care?

The maintenance and maintenance of cars is a passionate thing for car owners. However, we neglected some things in daily maintenance and maintenance, making our car not get better because of your maintenance. However, they suffered some "destruction."

Misunderstanding of a fluid addition: Rather than more or less when entering the winter, the replacement and addition of automotive fluids has become an essential maintenance content, many owners believe that only the full oil can be better protected Car engine. In fact, the oil in the crankcase can neither be added nor increased. When the oil is insufficient, the bearing and the journal can be lubricated, which can increase the wear and even cause the burning of the shaft. However, too much oil, the engine also has to fail, that is, crankshaft shank, large end of the connecting rod will produce violent agitation at work, will increase the engine internal power loss, but also make the oil splashed on the cylinder wall increased, resulting in burning oil malfunction. Too much oil can lead to increased carbon deposits in the combustion chamber and reduce engine power, which affects emissions.

When the owner checks or adds oil, it should be added according to the scale above the oil scale. The maximum oil level cannot exceed the upper limit of the scale. The minimum must not be lower than the lower limit of the scale. The oil level is usually added to the middle of the two scales. More appropriate.

Misunderstanding 2:

Tire pressure test: Ning Gao can not be low Some owners like to tire pressure is very high, that this can not only overload but also save fuel. However, in fact, this approach is not acceptable. Excessively high tire pressure will reduce the contact surface between the tire and the ground, and will increase the tread wear and reduce the braking effect when braking. Of course, too low tire pressure is not good, in addition to affecting traffic safety and braking effect, it will also accelerate the wear of the shoulder and increase vehicle fuel consumption. When the owner uses the air pump to inflate himself, he should inflate it in accordance with the air pressure specified by the manufacturer. The tire pressure label is usually located at the upper part of the body or the fuel tank cap.

Misunderstanding three:

External maintenance: The more waxing the better. In order for the car to maintain a beautiful appearance for a long time, many owners are accustomed to waxing the car regularly. Indeed, waxing can make a car look brighter, but it does not mean that frequent waxing can maintain the gloss of a car's paint finish. According to industry insiders, the performance of various car waxes is different, and their effects and effects are not the same. Care must be taken when selecting them. Improper selection will discolor the car paint.
