Modern mineral base oils are the result of a long and complex distillation and refining processes. The feedstock used is crude oil. This substance is not of uniform quality but consists of several thousands of hydrocarbon compounds in which the elements carbon and hydrogen are present in all molecules and, in part, are bound to other elements. The hydrocarbons can be divided into three main groups: paraffinic, naphthenic and aromatic. Paraffinic hydrocarbons can be further divided into two subgroups: normal paraffinic and iso- paraffinic. Paraffinic hydrocarbons are the best lubricants. The distillation process in the refinery separates the hydrocarbons contained in the crude into cuts based on the molecule size. Furthermore, as many unwanted substances as possible are removed in the process, such as sulphur, aromatic hydrocarbons, paraffin wax, etc. In other words the mineral oil production process is physical cleaning and the end product is so-called paraffinic base oil. Most of the hydrocarbons in the base oil are paraffinic, but it also contains naphthenic and aromatic molecules. When the finished lubricant, such as motor oil, is made of these, several additive compounds are used to improve the base oil properties. The final outcome can also be so-called naphthenic base oil, where most of the hydrocarbons are naphthenic. Their cold properties are excellent.

Base oil can be obtained from oil or non-oil sources. virgin base oil obtained from crude oil .Since most of the base oil used in the production of lubricants obtained from oil resources. base oil properties of the oil obtained is dependent on the type of crude oil and refining operations. base oil is chemical components during the refining process of crude oil from which it obtained, to inherit. Since crude oil containing different combinations such as paraffinic hydrocarbons, naphthenic and aromatic sulfur compounds are also, base oil are also made up of these compounds. base oil composition comprising a major effect on the properties of spent oils, paraffinic compounds, naphthenic and aromatic
