VMGZ oil (TU 38.101479-86) is the low-viscosity low cold-test mineral basis produced by means of hydrocatalytic process, solidified polymethacrylate additive an additive. Contains additives: antiwear, antioxidizing, antifoamy.
Oil is intended for systems of a hydrodrive and hydromanagement of the building, road, lumbering, hoisting-and-transport and other cars working on open air at temperatures in working volume of oil from -40°C to +50°C depending on type of the hydropump. For northern regions it is recommended as all-weather, for an average geographical zone — as winter.

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 mehaniko-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.
