Lubricating oil viscosity: how does it change with temperature?
Lubricating oils and thermo-viscosity
Amongst the fundamental characteristics of a lubricating oil, viscosity represents the most important property, together with the chemical composition.
A lubricating oil, while promoting smoothness and protection from mechanical wear between two surfaces in reciprocal movement, introduces a friction whose value is closely related to its viscosity at a given operating temperature.
