Don’t Get Fooled by Cold Kinematic Viscosity Oil Ads

A Motor Oil’s Kinematic Viscosity Is Only a Factor When the Engine is At Operating Temperature Kinematic viscosity is a measure of motor oil’s resistance to flow and shear due to gravity. It’s an important measure of a motor oil’s flow rate when the engine is warm. It’s measured in seconds-to-empty. In other words, it’s the time required to flow a fixed volume of oil by gravity through a calibrated orifice or capillary at a controlled temperature. That value is then converted into centistokes (cST) or square millimeters per second. … Read More
