Difference Between Summer and Winter Engine Oil

[VonJesse]

The difference between summer and winter engine oil lies in their viscosity. Winter engine oil has lower viscosity, while summer engine oil has higher viscosity. In winter, the temperature is low, and using oil with excessively high viscosity can lead to insufficient fluidity, increasing engine wear and resistance. In summer, the temperature is high, and using oil with excessively low viscosity can result in inadequate lubrication. Below are the specific grades for high-temperature and low-temperature environment-specific engine oils: 1. High-temperature environment-specific engine oil grades: SAE30, SAE40, SAE50, etc. 2. Low-temperature environment-specific engine oil grades: SAE0W, SAE15W, SAE20W, etc.
