What is the difference between Shell 5w20 and 0w20?
1 Answers
Shell 5w20 and 0w20 differences: Different viscosity: The viscosity of 0w20 engine oil is lower than that of 5w20. Regardless of the brand, engine oils use the unified SAE grade classification. The winter oil grades for engine oil viscosity classification are: 0W, 5W, 10W, 15W, 20W, 25W. The symbol W stands for winter, and the smaller the number before W, the lower the low-temperature viscosity and the better the low-temperature fluidity. Different applicable temperatures: 5w20 is suitable for a temperature range of -30°C to -35°C; 0w20 is suitable for a temperature range of -35°C to -40°C. "0W" means it can start normally at temperatures as low as -35°C. Different starting performance at low temperatures: The number before W represents the fluidity at low temperatures. The smaller the number, the better the starting performance at low temperatures. Therefore, 0w20 has better starting performance at low temperatures than 5w20.
