To determine the quality of oils, there is the concept of viscosity index. The viscosity index is defined as the difference between the viscosity of an oil measured at high and low temperatures. The larger the difference, the lower the viscosity index, the smaller the difference, the higher the viscosity index.

VHVI engine oils produced using VHVI hydrocracking technology have a very high viscosity index, providing reliable protection for any engine.

Oil additives are substances that enhance the positive properties of base oils and give them the necessary new properties. The global production of additives is estimated at millions of tons per year and is an important branch of the petrochemical industry. Most additives are multifunctional. Their total amount in commercial oil reaches 15-20%. Typically, engine oil contains the following additives:

– Viscosity additives,

– Anti-wear additives,

– antioxidant additives,

– Detergent additives (Detergents),

– Dispersed additives (Dispersants),

– Anti-corrosion additives,

– Antifreeze additives,

– anti-foam additives,

– Anti-seize additives…
