Base oil

Base 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 is produced by means of refining crude oil. This means that the 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, you can obtain extremely pure base oils, which are suitable when quality requirements are particularly stringent.

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.



Base oils are refined base stocks recommended for use in the manufacture of automotive & industrial lubricants, oil & greases, rubber products, white & paraffin oil and so on. Iranian Base oils are refined from crudes with characteristics making them the most desirable for our customers.

Base oils are more polar in nature than Paraffinic oils and hence they have good cooling properties and excellent low-temperature properties. They also have better solubility and ability to form stable emulsions.  ROYAL GLOBAL  ENERGY offers base oils in various viscosity range including SN 90, SN 150, SN 350, SN 500.SN650 GROUP I

Storage and Handling

  • Use PVC, nitrile or other oil resistant gloves and protective clothing to prevent skin contact. Where eye contact is a potential hazard, goggles should be worn.
  • Avoid temperatures above 80°C and strong oxidizing agents.
  • Ambient temperatures and atmospheric pressures normally encountered within buildings or roofed-over outdoor storage areas are acceptable.
  • Avoid entering areas where mists or vapours have built up as a result of abnormal temperatures or pressures without the proper breathing equipment and protective clothing.
