EN Oils are used in various lubrication systems, such as internal combustion engines, transmissions, hydraulic systems, and specialized industrial applications. The aim of this study is to show how the kinematic viscosity of oils for various applications changes with temperature. Sixteen different commercially available oils were evaluated, from the group of engine oils, transmission oils, hydraulic oils, shock absorbers, chain saw lubrication oils, air conditioning oils, hybrid vehicle internal combustion engines, and two-stroke engine fuel mixtures. Kinematic viscosity was measured for two temperatures, that is, 25 °C and 50 °C. For the purposes of the study, an Ostwald-Pinkiewicz capillary viscometer was used. According to the theory, the kinematic viscosity of all 16 oils tested decreased with increasing temperature. Knowledge of the viscosity behavior of oils in the group of engine oils, transmission oils, hydraulic oils, and specialized applications is of great importance, especially when considering the pumping resistance in gear pumps.
