The viscosity index (VI) is an arbitrary, unit-less measure of a fluid's change in viscosity relative to temperature change. It is mostly used to characterize...

antiwear additives, detergents, dispersants, and, for multi-grade oils, viscosity index improvers.[citation needed] The main function of motor oil is to reduce...

The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness":...

fluid; density, viscosity, viscosity index (VI), pour point and flash point, and solubility information from aniline point or viscosity-gravity constant...

Additives deliver reduced friction and wear, increased viscosity, improved viscosity index, resistance to corrosion and oxidation, aging or contamination...

Hydrotreating. Group II+ base oils have a high viscosity index at the higher end of the API Group II range. The viscosity index is 110-115 minimum. Originating in...

Viscosity depends strongly on temperature. In liquids it usually decreases with increasing temperature, whereas, in most gases, viscosity increases with...

various lubricants according to their viscosity behavior as a function of temperature, in 1929 the viscosity index (V.I.) was introduced by Dean and Davis...

the apparent viscosity is constant, and equal to the Newtonian viscosity of the fluid, but for non-Newtonian fluids, the apparent viscosity depends on the...

that include: high lubricity, polarity, low traction properties, high viscosity index, controlled quenching speeds, good temperature stability and low wear...
