The physical properties of lubricants include important characteristics like viscosity, shear stability, high- and low-temperature performance, water resistance and volatility. Lubrication science seeks to optimize a lubricant’s performance by managing these properties through the use of different base oils and additives. Of the fundamental physical properties, viscosity – the measure of the internal friction of a liquid, or its resistance to flow – is one of the most critical.
