Base oils are used to manufacture products including lubricating greases, motor oil and metal processing fluids. Base oil is typically defined as oil with a boiling point range between 550 and 1050 F, consisting of hydrocarbons with 18 to 40 carbon atoms. This oil can be either paraffinic or naphthenic in nature depending on the chemical structure of the molecules.

Base oils are the building blocks used to manufacture motor oils and other lubricants like grease, lube oils. etc.
