The Russian lubricants market is steadily showing a steady growth trend. At the same time, a significant share of the turnover is accounted for by products oriented to industrial operation under conditions of large temperature differences and high loads. A worthy place in this segment is occupied by VMGZ oil (off-season thickened hydraulic oil), which, due to its unique composition, ensures uninterrupted operation of equipment equipped with hydraulic drives in the areas of the Far East, Siberia and the Far North.
Application area
The purpose of VMGZ is a working environment for hydraulic systems (hydraulic pumps, hydraulic controls, hydraulic drives) of drilling rigs, elevators, vehicles, agricultural machinery, forestry and construction machinery, and industrial equipment. Manufacturers recommend using this type of oil in central Russia at low temperatures (it is understood that VMGZ hydraulic oil is used in outdoor equipment) and the northern regions (regardless of the season).
A few words about manufacturers and technology
Among the leading Russian producers of off-season hydraulic thickened oil are four reputable companies with a worthy business reputation. These are Lukoil, Gazpromneft, Syntoil, TNK.
As the basic basis of the future final product, high-quality selective sulfur-containing oils with low sulfur content are used, obtained as a result of hydrocracking of oil fractions or deep dewaxing. Such a basis is characterized by a minimum dynamic viscosity and a low pour point. The operational and physico-chemical characteristics that VMGZ oil should have are provided by adding an effective composition of functional additives (anti-corrosion, anti-foam, anti-wear, anti-oxidative, etc.).

Benefits
Using off-season hydraulic thickened oil during the operation of specialized machinery and equipment, consumers are able to:
- protect hydraulic components from corrosion damage and mechanical wear;
- ensure uninterrupted operation of equipment in a wide temperature range (from + 50 ° to - 40 ° );
- start the hydraulic drive, bypassing the preheating stage;
- minimize the need for oil changes (including seasonal) due to the high rates of chemical and antioxidant stability of VMGZ;
- due to the antifoam properties, to avoid excessive losses of the working fluid in the presence of an effective level of cooling and lubrication of the surfaces, which is very important for high-speed mechanisms such as hydraulic systems.
Why is quality important?
Low-quality VMGZ oil can cause a number of problems. Among the most critical, we highlight the following negative consequences:
- increased pollution of the hydraulic system;
- clogging of filters;
- increased wear and corrosion of parts.
As a result, equipment prematurely fails, risks associated with downtime or production shutdown arise, and maintenance costs increase.
How to choose a quality product?
For the consumer of a product such as VMGZ hydraulic oil , performance is paramount. However, products of the same class, offered by various manufacturers of lubricants, have approximately the same technical indicators. This fact is due to the use of a similar basic set of additives. In addition, each company, striving to take a stable position in the fierce competition, relies on certain important properties of the final product. For example, we can talk about anticorrosive or temperature (the limit bar of solidification and fire) indicators.
Therefore, the rules that should be followed when choosing VMGZ oil can be formulated as follows:
- Carefully read the attached instructions, paying attention to the compliance of the product with generally accepted international standards (ISO, SAE).
- Do not rely solely on the price segment, the determining criterion should be the credibility of the brand.
Good luck with your choice and smooth operation of your equipment!
