WebThe SAE number (also known as “viscosity rating” or “viscosity grade”) is a codeto grade motor oils by their viscosity characteristics. The SAE viscosity grade is not the actual viscosityvalueof the motor oil. Originally, viscosity ratings were monograde— meaning it was only one number (like engine oil SAE 30). WebFeb 2, 2016 · Viscosity index is a dimensionless number that represents how the viscosity of a hydraulic fluid changes with temperature. (It also applies to fluids like engine and automatic transmission oils, gear lubricants, and power-steering fluids.)

WebFor instance, an SAE 80W gear lubricant may have the same viscosity as an SAE 20W or SAE 30 engine oil and SAE 90 gear lubricant viscosity can be similar to that of an SAE 40 … WebThe numbers in the code have nothing to do with viscosity index.
