Can Winter Engine Oil Be Used in Summer?

[DelArya]

Generally, it is possible, but not recommended. Most engine oils available on the market today are all-season oils. Unless you are in an extremely cold or extremely hot region, there should generally be no issues. The specific situation depends on the local temperature. For example, winters in Northeast China and winters in Southern China are certainly not the same. Whether it can be used depends not only on the local temperature but also on whether it meets the engine oil grade requirements of the vehicle. Introduction to Engine Oil Grades: 1. The smaller the number before the 'W,' the better the low-temperature performance. 2. The larger the number after the 'W-,' the higher the viscosity of the oil, making it suitable for high-temperature environments caused by high ambient temperatures and heavy engine loads.
