“I often hear the term ‘bright stock’ in reference to certain oils. Can you explain what this term means and how bright stock oils are different than other oils?”
The term “bright stock” refers to the base oil. Generally, a Group I base oil is described as either solvent neutral (SN) or bright stock (BS). These types of oils are used in the production of lubricants and lubricant additives but usually do not include additives.
