What Type of Engine Oil Should Be Used for Sedans in Winter?

[VanAdalynn]

Automobiles should use W-grade engine oil in winter. Below are the characteristics and classifications of winter engine oil: Winter engine oil must have three characteristics: low viscosity, low pour point, and good anti-wear properties: Winter engine oil must meet the three major characteristics of low viscosity, low pour point, and good anti-wear properties to provide adequate protection for the engine. Winter temperatures are relatively low, so the fluidity of engine oil in cold conditions is poor. Therefore, winter engine oil needs to have good low-temperature fluidity. Classification of winter engine oil: The winter oil grades before the W in the oil label are: 0W, 5W, 10W, 15W, 20W, 25W. The symbol W stands for Winter, and the smaller the number before the W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. The number represents the low-temperature fluidity of the engine oil.
