Summer car repair and maintenance must read[汽车修理知识]

Gasoline cannot be used at a reduced price
 A survey report shows that more than 80% of car owners should use gasoline above 93, and among these 80% of car owners, nearly 60% have chosen the wrong gasoline label, including lowering the standard and using over-standard gasoline. Experts pointed out that the impact of excessive fuel consumption on the car in the short term is not obvious, but long-term use will shorten the service life of the car.Long-term reduction in fuel consumption in order to save money will cause greater damage to the car.
The hazard is particularly obvious when exposed to temperatures above 30°C, so special attention should be paid to the correct use of gasoline in summer.
lubricating oilBeware of overheating and deterioration
There are also some special requirements for lubricating oil in summer cars. Long-term operation of the engine in a high temperature environment will transfer heat to the lubricating oil, causing the lubricating oil to oxidize and deteriorate, affecting its lubrication function. Since the lubricating oil plays a decisive role in the normal operation of the engine, long-term use of inferior lubricating oil or degraded lubricating oil may cause gelling in the oil circuit and cause oil alarms; in severe cases, vicious accidents such as cylinder pulling, bush burning and axle holding may occur. . Therefore, car owners should pay special attention to lubricants in summer, and replace them in time if they find it deteriorates.
also used in summerAntifreeze
Many car owners think that adding antifreeze is a matter of winter, and it is enough to add some tap water in summer. Experts clearly pointed out that antifreeze should also be used in summer.
A good antifreeze not only has the function of cooling the engine, but also has good low temperature and high temperature resistance, and even has the functions of anti-corrosion and rust removal. Therefore, it is not advisable to replace the antifreeze with water.First, the water pairCooling systemThere will be some corrosion, and the antifreeze contains anti-corrosion and anti-rust additives. Secondly, the boiling point of antifreeze is above 120°C, while the boiling point of water is only 100°C. Using antifreeze can prevent the car from boiling in summer. In addition, the use of water instead of antifreeze is easy to generate scale and needs to be replaced frequently, but there is no such worry when using antifreeze.
