What are the precautions for using cars in winter?

[ReidLynn]

Precautions for using cars in winter include replacing winter tires, adding or replacing antifreeze, and selecting suitable engine oil. The specific precautions are as follows: Replacing winter tires: As the temperature drops, the surface of the tires becomes stiff, which can affect the grip performance of the tires. In some cases, this may lead to slipping, especially in northeastern regions where rain and snow are frequent, making road conditions worse. Additionally, due to the effect of thermal expansion and contraction, tire pressure will also decrease. Adding or replacing antifreeze: Antifreeze has two main functions. In summer, when temperatures are higher, antifreeze ensures the normal operation of the car's cooling system, preventing the engine from overheating. In winter, it prevents excessively low temperatures from freezing and damaging engine cylinders and other components. Selecting suitable engine oil: Similarly, due to the drop in temperature, if the cold-start engine oil is too thick in winter, it can affect car starting and increase engine wear. On the other hand, if the hot engine oil is too thin, it can reduce lubrication and sealing performance.
