VMGz oil

VMGZ oil (TС 38.101479-86) is a low-viscosity low cold - test mineral base produced using hydrocatalytic processes, thickened with a polymethacrylate additive. Contains additives: antiwear, antioxidant, antifoam. It is used for hydraulic drive and hydraulic control systems of construction, road, logging, lifting and conveying equipment and other machines operating in the open air at temperatures in the working volume of oil from -40 ° C to + 50 ° C, depending on the type of hydraulic pump. For the northern regions, VMGZ oil is recommended as an all-season oil, for the middle geographic zone - as a winter one.
