Viscosity is an important fluid property when analyzing liquid behavior and fluid motion near solid boundaries. The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. The shear resistance in a fluid is caused by inter-molecular friction e...

The viscosity index (ASTM D2270) is a widely used measure of the variation in kinematic viscosity due to changes in the temperature of fuels between 40°C and 100°C (104°F and 212°F). From: Encyclopedia of Analytical Science (Third Edition), 2019 ...
Of all the tests employed for used oil analysis, none provides better test repeatability or consistency than viscosity. Likewise, there is no property more critical to effective component lubrication than base oil viscosity. However, there is more to viscosity than meets the eye. Viscosity can be ...
