WebFeb 24, 2024 · The viscosity is measured from the required torque to rotate the spindle against the oil shear stress. And thus way dynamic viscosity of the oil is measured & expressed in Centipose (cP). This method is described in ASTM D2983 and is also known as the Brookfield method. To understand the formulation of multigrade engine oil like … WebThe numbers after the “XW” indicate viscosity at 100 degrees Celsius and represent the oil’s resistance to thinning at high temperatures. For instance, oil with a 5W-30 grade thickens less than oil with a 10W-30 grade in cold weather. Oil with a 5W-30 grade thins out more quickly at high temperatures as compared to oils with a 5W-40 grade. rescare greencastle indianaWebdynamic viscosity. In engines, the density of the lubricant continu-ously changes due to changes in particle content and temperature. Hence, dynamic viscosity is the true indicator of oil quality.
