5 items of winter escorts should be used to choose high-quality composite oil

[Car owner's home car knowledge]As the weather gradually gets colder, how to maintain various performance indicators of the car in low temperatures is the primary guarantee for drivers to drive safely. Experts believe that special attention should be paid to parking outdoors in winter to avoid "frostbite" in vehicles.

Parking at night, open windows to cool down and prevent frost

Master Li, a technician at Chengdu Chess Store, has been engaged in the car maintenance industry for more than 10 years. He gave suggestions: "In low temperatures, vehicles often experience glass frosting in the early morning, which is mainly caused by the large temperature difference between inside and outside the car. Therefore, when you go home to park at night, it is best to open the car window for a few minutes to reduce the temperature inside the car, so as to reduce the frosting of the windshield when driving in the early morning."

It is best to change the antifreeze once every two years

"In low temperature weather, if the vehicle is running normally, it is necessary to ensure sufficient antifreeze. The owner of the car should check regularly whether the vehicle is lacking in liquid or whether it has deteriorated." Master Li introduced that if there is a problem with the antifreeze, the impact may be great, "it may block the pipeline and even corrode and damage the cylinder. Therefore, use antifreeze with caution, do not mix it, and do not use counterfeit and shoddy products." Master Li suggested that the antifreeze should be replaced once every two years, and it is best to rinse the cooling system with clean water before replacement.

In winter, parking is suitable for buildings

Because the temperature in winter is too low, the oil viscosity increases and the resistance becomes larger, the engine cold start reaction speed is slow, and this fault is more obvious in old cars. To improve this situation, Master Li has a little tip, "In winter, it is best to put the front of the car facing the building, so that the building can be used to block the wind and prevent the engine from being blown by the cold wind. When parking at night, you can turn the front of the car facing the sun to the sun and let the sunlight shine on the front of the car as soon as possible to help the engine heat up."

It is best to choose high-quality composite oil in winter

"In low temperature weather, excessive thick oil in cold car will affect the start-up, resulting in wear of large parts, while excessive thin oil in hot car will reduce lubrication and sealing performance." Master Li suggested that you try to choose high-quality composite oil suitable for winter. If it is time to change oil, it is best to replace it before the weather becomes cold.
