Owners gradually know that the car needs to be repaired in three parts and maintained in seven parts. Of course, maintenance cannot be allowed.carKeep your youth forever, but in car maintenance, some car owners over-respect and damage the car. In fact, this is only when the car owner knows little about maintenance. The maintenance experts will tell you the four wastes of maintenance.
The first type of waste: maintenance is too "diligence"
Ms. Zhao is a blind car. She often receives maintenance information from dealers. The new car has only been driven for 8,000 kilometers. Ms. Zhao’s oil has been changed three times, and the machine filter has also been changed three times. The maintenance interval is less than 3,000 kilometers.
remind: car maintenanceCycle refers to the interval mileage or time of car maintenance. High maintenance frequency is not a bad thing, it can more effectively protect the performance of the vehicle, but too frequent is unnecessary. Scientifically determining the interval mileage of various maintenance operations can keep the car in good technical condition and save maintenance and repair costs.
The second waste: the pursuit of high-grade gasoline
He thought that the higher the gasoline mark, the better Mr. Zhang, because of his love for his new car, he has been adding No. 97 gasoline to his car for two years.
Reminder: Generally, car owners know that if high-end cars use low-grade gasoline for a long time, in addition to knocking (commonly known as knocking), problems such as power drop, fuel consumption increase, and damage to internal parts of the engine will occur, which will seriously shorten the life of the engine. Therefore, many car owners prefer not to overuse, and prefer to use high-standard fuel. In fact, the higher the car’s label, the better, even for high-end cars, it does not mean that higher fuel standards must be added.
The third waste:tireTo be imported
Some people buytireEspecially like to emphasize "import", Mr. Chen who is playing car is like this. But after several experiences, Mr. Chen discovered that the new tires introduced abroad are not suitable for domestic users. Once, he only ran the mountain road once with his new tires, and the sidewall was covered.
Reminder: There is a big difference between smooth foreign roads and domestic roads. Tyres suitable for foreign roads may not perform well on domestic roads, especially the impact resistance of the sidewalls.
After some foreign brand tires are produced by domestic joint ventures, a layer of cord fabric is added to the side of the tires according to the domestic road conditions, which greatly enhances the impact resistance of the sidewalls. The joint venture tires can completely replace imported goods in terms of performance. , And the price is more affordable.
The fourth waste: too much oil
The owner of the new car, Xiao Wang, had just passed the 5,000-kilometer warranty. Xiao Wang, who learned to look at the oil gauge, ran the 2000-kilometer high-speed on May 1st. He was afraid that the oil would not be enough, so he added a bottle of oil from a friend. Who knows that not long after, his new car started to burn engine oil.
Reminder: This is because there is too much oil in Xiao Wang's new car.When the engine is workingCrankshaftThe handle and the big end of the connecting rod will produce violent agitation, increase the internal power loss of the engine, and increase the oil splashing on the cylinder wall, causing oil burning failure. The oil in the engine oil pan should be controlled between the upper and lower engraved lines on the oil dipstick.
