Can 10w-40 engine oil be used in winter?

[DelLincoln]

10w-40 engine oil can be normally used in winter at temperatures of -25°C and above. The explanation is as follows: 1. Meaning: 10w-40 is the SAE standard viscosity value, where W stands for WINTER. The winter oil grades are: 0W, 5W, 10W, 15W, 20W, 25W. The smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. The number after W represents the kinematic viscosity of the oil at 100°C. The higher the number, the higher the viscosity. 2. Introduction: The freezing point temperature corresponding to 10W engine oil is -25°C, which means it can withstand an external low temperature of -25°C; 40 represents that the kinematic viscosity standard at 100°C is between 12.5mm2/s and 16.3mm2/s.
