What is the Difference Between 5W and 0W Engine Oil?
1 Answers
Both 0W and 5W engine oils are winter-grade oils, where 'W' stands for 'Winter' in English. The number preceding the 'W' indicates the oil's low-temperature fluidity. The following points highlight the differences between 5W and 0W engine oil: 1. Different low-temperature viscosity: The smaller the number, the lower the low-temperature viscosity of the oil, resulting in better fluidity and greater resistance to cold. The difference between 0W and 5W lies in the fact that 0W has better low-temperature fluidity than 5W. 2. Different cold resistance: Generally, 0W oil can withstand temperatures as low as -35°C, while 5W oil can only tolerate temperatures down to -30°C. 3. Different suitable environments: 0W oil is easier to start in cold weather compared to 5W oil, making it a better choice for northern regions with lower winter temperatures. In southern regions where winter temperatures are not as low, 5W oil is more suitable.
