Volnovka is a global lubricant supplier, delivering market-leading lubricants to consumers in over 100 countries. Volnovka Lubricants brings world-class technological insights to its products, offering you the best formulations for your vehicle.

The main properties of our lubricants, which are usually indicated in the technical characteristics of the our product, are:

  • Viscosity
  • Viscosity index
  • Pour point
  • Flash point
Viscosity

Viscosity describes the flow behaviour of a fluid. The viscosity of lubricating oils diminishes as temperature rises and consequently is measured at a given temperature (e.g. 40C). The viscosity of a lubricant determines the thickness of the layer of oil between metallic surfaces in reciprocal movement.

The most widely used unit of measurement of viscosity is the centistoke (cSt).

Viscosity index

The viscosity index is a characteristic used to indicate variations in the viscosity of lubricating oils with changes in temperature.

The higher the level of the viscosity index, the lower the variation in viscosity at temperature changes.

Consequently, if two lubricants with the same viscosity are considered at a temperature of 40C, the one with the higher viscosity index will guarantee:

  • better engine start up at low temperatures (lower internal friction)
  • a higher stability of the lubricating film at high temperatures
Viscosimetric classifications

There are a number of viscosimetric classification systems that indicate, usually with a number, a more or less limited viscosity range.

The aim is to provide, along with the viscosity index, a rapid indication of the most appropriate choice of lubricant for a specific application.

ISO VG degrees are widely used to classify industrial oils. Each degree identifies a kinematic viscosity gap measured at 40C.

SAE degrees are used in the field of engine oils and gear oils.

Pour point

The pour point refers to the minimum temperature at which a lubricant continues to flow. Below the pour point, the oil tends to thicken and to cease to flow freely.

Flash point

The flash point is the minimum temperature at which an oil-vapour-air-mixture becomes inflammable. It is determined by progressively heating the oil-vapour-air-mixture in a standard laboratory receptacle until the mixture ignites.
