Oil AU (TOR 38) is produced from low-sulfur and sulfurous paraffinic petroleums with use of processes of deep selective clearing by phenol and deep dewaxing.
Contains an antioxidizing additive. Ensures functioning of hydro drives from — (30-35) °C to + (90-100) °С.

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.
