What is the difference between Castrol Edge FE and SN?
1 Answers
Introduction to the differences between Castrol Edge FE and SN: 1. Different properties: The FE engine oil contains the latest titanium fluid formula and does not belong to the category of engine oil grades, such as SN, which refers to the oil grade. 2. Different grades: The 'S' in SN stands for lubricating oil for gasoline engines, and 'N' represents the grade, which is arranged in the sequence of the 26 English letters. Currently, the highest grade is N. The 5w-30FE has no grade. 3. Different viscosities: The number before the W represents the flow viscosity under low-temperature conditions. The smaller this number, the better the low-temperature fluidity of the oil, and the better the protection for the engine during cold starts. The number after the W is the viscosity of the oil at 100°C. The higher the number, the higher the viscosity, and the better the protection for the engine under high temperatures.
