Base Oil



Base oils are used to manufacture a wide range of lubricating products, from motor oils to greases and emulsions. They come in five Groups, and can be produced from refining crude oil or created synthetically.

There are large numbers of crude oils all around the world that are used to produce base oils. 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 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.

Iranian Base oils are refined from crudes with characteristics making them the most desirable for our customers.

Work and Energy offers base oils in various viscosity range including SN 150, SN 350, SN 500 and SN650.
