Understanding Oil Viscosity: The Thick and Thin of It If you have a gearbox with a manufacturer’s nameplate instructing you to use the American Gear Manufacturer’s Association (AGMA) #4 viscosity oil at a given operating temperature, or if it specified a 750 SSU viscosity oil, would you know exactly what viscosity oil you need? If…

How Important is Oil Viscosity?
The Fundamentals of Viscosity The most important single property of a lubricant is its viscosity. It is defined as a measure of a lubricant's resistance to flow. The viscosity of any fluid changes inversely with temperature. As temperature increases, viscosity decreases and as temperature decreases, viscosity increases. The most common way that viscosity is measured…
