Petroleum Lubricating oils are made from heavier portion of Crude Oil that remains after removal of the higher fractions. Till recently Lubricant manufacturing companies have been using GROUP I Base oil. In Group I processing, older and general older technology is adopted where in base oils are produced by solvent refining and solvent Dewaxing technology. More modern base oils using hydro processing technology fall into the Group II & III which are vast improvement over Group I base oils.
