It’s all about the base

Base oils are the foundation for the preparation of a huge variety of hydrocarbon products. The best known of them are the lubricants.  Base oil is produced from refining crude oil or through chemical synthesis. Consisting of hydrocarbons with a length of 18 to 40 carbon atoms, base oils can be either paraffinic or naphthenic in their character depending on the chemical structure and origin of the molecules.

Paraffinic base oils are used mainly to prepare automotive lubricants, as the viscosity behaves the best under temperature variations.  They are also the base to manufacture maritime and railway lubricants, industrial oils, lubricating greases and pharmaceutical products, such as mineral oil.

Naphthenic base oils are used to manufacture insulating oils for transformers, lubricating greases, cutting fluids, oil for compressors and oil for shock absorbers. They can also be used as rubber plasticizers.

 

What group do you identify with

Group I base stocks contain less than 90 percent saturates and/or greater than .03% sulfur and have viscosity index greater than or equal to 80 and less than 120.

Group II base stocks contain greater than or equal to 90 percent saturates and less than or equal to .03% sulfur and have viscosity index greater than or equal to 80 and less than 120.

Group III base stocks contain greater than or equal to 90 percent saturates and less than or equal to .03% sulfur and have viscosity index greater than or equal to 120.

Group IV base stocks are polyalphaolefins (PAO).

Group V base stocks include all other base stocks not included in Group I, II, III, IV.
