Four Kinds of Waste in Automobile Maintenance Knowledge

The owner of the car should know that the car must be "three-point repairs, seven-point maintenance," and of course maintenance should not allow the car to remain young. However, in the maintenance of cars, some car owners are also overly caring and damaging the car. The conservation expert tells you about the four kinds of wasted conservation.

The first kind of waste: maintenance is too "difficult." Ms. Zhao is a car blind. She often receives maintenance information from dealers. The new car only opened 8,000 kilometers. Miss Zhao's oil has been changed 3 times, the machine filter has also changed 3 times, and the maintenance interval mileage is not 3,000 kilometers. To. The vehicle maintenance cycle is the interval or time between car maintenance. The high frequency of maintenance is not a bad thing. It can more effectively protect the performance of the vehicle, but it is not necessary too often. Scientifically determining the interval between various types of maintenance operations can enable the car to maintain a good technical condition, as well as save maintenance and repair costs.

The second waste: the pursuit of high-grade gasoline. I think that the higher the better the gasoline label, Mr. Zhang, because he loves the new car, he has been giving gasoline No. 97 to his car for two years. General car owners know that if high-end cars use low-grade gasoline for a long time, in addition to detonation, they will also cause problems such as power drop, fuel consumption increase, internal engine parts damage, etc., which will severely shorten the life of the engine. Therefore, many owners like to use high standard oil. In fact, the higher the number of gasoline labels, the better. Even high-end cars do not necessarily mean that they must increase their markedness.

The third kind of waste: tires are imported. Some people like to buy tires and like to emphasize "import". This is how Mr. Chen plays the car. However, after several experiences, Mr. Chen found that the new tires introduced abroad are not suitable for domestic users. On one occasion, his newly replaced tire only ran once on the mountain, and the side of the tire took a bag. Foreign flat roads are quite different from domestic road conditions. Imported tires do not necessarily perform well on domestic roads. In particular, the impact resistance of the sidewalls is obviously unacceptable. After the tires of some foreign brands are jointly produced in China, they have added a layer of cord fabrics on the side of the tire according to the domestic road conditions, which greatly enhances the impact resistance of the sidewalls. The tires produced by the joint venture can completely replace imported goods in performance. And the price is more affordable.

The fourth waste: too much oil. The new car of owner Wang Xiaowang just passed the first insurance of 5,000 kilometers. He learned to look at the king of the oil ruler and he ran a 2000-kilometer high speed. When he was afraid that the oil would not be enough, he added a bottle of engine oil sent by a friend. . It wasn’t long before his new car began to burn engine oil. This is because Xiao Wang's new car has too much oil. The crankshaft shank and the big end of the connecting rod will generate violent agitation when the engine is working, which increases the internal power loss of the engine and also increases the oil splashed on the cylinder wall, resulting in burning oil failure. The oil in the engine oil pan should be controlled between the upper and lower mark lines of the oil dipstick.
