What is the difference between winter engine oil and summer engine oil?
1 Answers
According to the characteristics of engine oil, when the temperature is low, the kinematic viscosity of the engine oil will increase, which may cause difficulty in starting the vehicle or increased fuel consumption. The differences between winter engine oil and summer engine oil are as follows: 1. Different viscosity: Winter engine oil has lower viscosity, while summer engine oil has higher viscosity. In winter, the temperature is low. If engine oil with excessively high viscosity is used, it will lead to insufficient fluidity, increased engine wear, and greater engine resistance. In summer, the temperature is high. If engine oil with excessively low viscosity is used, it will result in insufficient lubrication. 2. Usage differences: When the temperature is low, the kinematic viscosity of the engine oil will increase, which may cause difficulty in starting the vehicle or increased fuel consumption. When the temperature is high, the kinematic viscosity of the engine oil will decrease, reducing the lifespan of the engine oil. Therefore, the kinematic viscosity of engine oil used in winter should generally be chosen to be lower, which is commonly referred to as appearing thinner. As for engine oil used in summer, a higher kinematic viscosity should be selected, making the oil appear thicker.
