The cold wave is coming, the temperature plummets, and the car should be extra cared for in winter, and it is very important to use the right engine oil. Especially in the north, when the temperature is lower, the fluidity of the oil will deteriorate, and the less able it will protect the engine during cold starts, which will exacerbate engine wear.
When choosing engine oil in winter, in fact, many car owners understand that there are errors. In winter, it is necessary to change the low-viscosity engine oil, but it is not blind, no matter how it is replaced, it needs to meet the operating conditions of the engine, and it is necessary to select the engine oil according to the viscosity range recommended by the vehicle manual.
In the northern region in winter, it is recommended to choose the engine oil with a small value in front of W, because the temperature is low in winter, so the low temperature fluidity of the engine oil is required to be higher, and it is best to use 0W engine oil. The lower the number, the more resistant to low temperatures, the better the fluidity of the oil in winter. 0W means a minimum temperature of -35 and 5W can be operated at a minimum temperature of -30.
Summary:In addition to choosing the right oil, there are also small details to pay attention to, for example, when the car is just starting, it is better to keep the low speed for 3 to 5 minutes, just like we need to warm up before doing sports. This allows the oil to have a warm-up process and allows it to move throughout the cycle, so that it can perform better at high speeds.
