Generally speaking, when winter comes, everyone has heard of changing winter tires and antifreeze, however, it is rare to hear about changes in the engine oil. Some car owners or old drivers also change the oil of the car in winter. So do you need to replace the winter oil in winter? Today, Star Boy will tell you about the oil.
As the "blood" of the engine, the oil plays a lot of roles in the engine, including auxiliary cooling and cooling, sealing and leak-proof, shock absorption buffering, rust and corrosion prevention, lubrication and wear reduction. It is also important to choose the right oil for your vehicle, which can be classified according to the SAE viscosity class in winter, summer and four seasons.

The design temperature and operating conditions of the engine oil are clearly seen from the label, and in general, 5W-30 is a relatively common oil mark. So what do these numbers represent?
The smaller the value in front of W, the lower the low temperature viscosity, and the better the low temperature fluidity, indicating that the ambient temperature of the engine oil is lower. 0W and 5W represent the minimum operating temperatures of -35°C and -30°C, respectively.
<h1 class="pgc-h-arrow-right" data-track="16" > the classification of oils</h1>
There are 6 kinds of winter oils, 0W, 5W, 10W, 15W, 20W, 25W, W represents the abbreviation of winter Winter, the smaller the number in front of it, the greater the fluidity of the oil, the lower the applicable temperature, such as: 0W the minimum temperature is -35 ° C, 5W is the minimum temperature applicable to -30 ° C, and so on.
There are 5 kinds of summer engine oils, 20, 30, 40, 50, 60. The higher the number, the greater the viscosity of the oil, the stronger the high temperature protection performance, and can be applied to higher temperature environments.
There are 16 kinds of common in winter and summer, namely 5W20, 5W30, 5W40, 5W50, 10W20, 10W30, 10W40, 10W50, 15W30, 15W40, 15W50, 20W20, 20W30, 20W40, 20W50.

It can be seen that whether to replace the winter oil depends on your region, if it is the northeast, Xinjiang, you must use 0-30 or 0-40 or 5-40w oil, there is no extreme low temperature, generally use 5-40w oil, all seasons can be used! If there is a low temperature below -25 ° from time to time in winter, it is best to use 0 ~ 30 motor oil. Therefore, the car will not be frozen in winter, and it is generally not necessary to replace the special oil in winter. Of course, you should also pay attention to the oil label of your own model, and pay attention to maintenance. Only by loving a car can we survive the cold winter and bring warm space to everyone.
