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

[StKaleb]

In winter, cars require engine oil with higher fluidity and wear resistance, and winter-grade oil can be used. Below is more information about winter engine oil for cars: 1. The impact of low temperatures on engine oil: Low temperatures affect fluidity. In winter, when temperatures are low, engine oil becomes more viscous, turning into a semi-solid, semi-fluid state, which hinders smooth flow. Substandard engine oil can exacerbate engine wear. If the oil quality is slightly inferior, it may even stop flowing entirely. In such cases, the oil would take a long time to reach the engine. 2. Information about winter engine oil: There are six types of winter-grade oils. The winter-grade oil classifications are 0W, 5W, 10W, 15W, 20W, and 25W. The symbol 'W' stands for winter, and the smaller the number before 'W', the lower the oil's viscosity at low temperatures, the better its low-temperature fluidity, and the lower the minimum applicable temperature. For example, 5W can withstand external temperatures as low as -30°C, 10W up to -25°C, 15W up to -20°C, and 20W up to -15°C.
