Base Oil Grades

Azera Oil is one of reliable companies in base oil that supply all rc and permium base oil gradesBase oils are used to manufacture products including lubricating greases, motor oil and metal processing fluids. Different products require different compositions and properties in the oil. One of the most important factors is the liquid’s viscosity at various temperatures. Whether or not a crude oil is suitable to be made into a base oil is determined by the concentration of base oil molecules as well as how easily these can be extracted.

Base Oil Grades

Base oil is produced by means of refining crude oil. This means that crude oil is heated in order that various distillates can be separated from one another. During the heating process, light and heavy hydrocarbons are separated – the light ones can be refined to make petrol and other fuels, while the heavier ones are suitable for bitumen and base oils.

There are large numbers of crude oils all around the world that are used to produce base oils. The most common one is a type of paraffinic crude oil, although there are also naphthenic crude oils that create products with better solubility and very good properties at low temperatures. By using hydrogenation technology, in which sulfur and aromatics are removed using hydrogen under high pressure, extremely pure base oils can be obtained, which are suitable when quality requirements are particularly stringen.

Chemical substances – additives – are added to the base oil in order to meet the quality requirements for the end products in terms of, for example, friction and cleaning properties. Certain types of motor oils contain more than twenty percent additives.

Oil Viscosity Explained

When talking about motor oil, you’ll often hear the term ‘viscosity’ being used. Essentially, oil viscosity refers to how easily oil pours at a specific temperature. Thinner oils flow easier at lower temperatures and have a lower viscosity, whereas thicker oils have a higher viscosity.
In cold weather, thin oils reduce friction and help engines to start quicker. In higher temperatures, thick oils maintain oil pressure and film strength, and support heavier loads.
The viscosity index measures oil’s ability to resist changes in viscosity as temperature changes. Most multi-grade motor oils are formulated with viscosity index improvers, which use polymer additives to help maintain consistent oil viscosity over a wide range of temperatures—protecting engine parts from wear.
