Other lubricants like metal working fluids, lubricants and gear oils contain additives may be up to 30%.
It can be obtain from oil or non-oil sources. it optain from crude oil .Since most of the it use in the production of lubricants obtain from oil resources.
Virgin base oil properties of the oil obtained is dependent on the type of crude oil and refining operations. It is chemical components during the refining process of crude oil from which it obtain, to inherit.
Since crude oil containing different combinations such as paraffinic hydrocarbons, naphthenic and aromatic sulfur compounds are also. They are also make up of these compounds. It composition comprising a major effect on the properties of spent oils, paraffinic compounds, naphthenic and aromatic.
