Data on operational temperatures represent values, which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mechanical-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can affect work of components.
