Different types of base oil:
-
Paraffinic Base Oils (Often referred to as Group I or II)
-
Naphthenic Base Oils
-
Synthetic Base Oils (Often referred to as Group III, IV & V)
Paraffinic Base Oils:
Base Stocks produced using solvent refined & advanced hydrocracking processes. Some of the further developed oils also involve a catalytic de-waxing process to produce a more pure product. The aromatic content of these oils varies by the refining process used.
Naphthenic Base Oils:
Refined from sweet crude oil distillates. Naphthenic base oils have a very low aromatic content and low paraffin (Wax) content. These characteristics allow for a low pour point on lighter viscosities and a high degree of solvency where heavier viscosities are required.
Synthetic Base Oils:
Base stocks that involve a chemically modified base which can be of a petroleum or chemical origin. Group III - Base Oils that have been converted by means of a catalytic process in the presence of Hydrogen, usually under greater pressures. These resulting Base Oils are very pure and refined with superior performance to Group I and II Base Stocks.
We offer Group I, II and III base oils from our strategically placed terminals in the Middle East and South East Asia,
Attached are results for reference only. Actual results should refers to Certificates of Analysis (COA) of the actual cargo.
Group I
Group I These oils are usually processed with solvents and they have a good degree of solvency, but they are most vulnerable to oxidation and thermal degradation compared to oils processed in different manner. The oils of Group I are used in almost all applications in the automotive and industrial field and are important for the formulation of lubricating greases.
Group II
Group II Oils subjected to mild hydrocracking and catalytic de-waxing. They have high saturation levels, and good performance in terms of thermal and oxidation stability. These oils are used in a large range of automotive and industrial applications.
Group III
Group III Typically subjected to severe hydrocracking, advanced catalytic de-waxing, and / or hydro-isomerization, they have high viscosity indexes and very good thermal and oxidation stability. They are used primarily in the automotive sector.
Group IV
Group IV Oils produced synthetically. The main characteristics relate to low pour points, high viscosity indexes, excellent thermal stability and excellent oxidation stability. These oils are used primarily in the automotive industry, such as high-quality motor oils and transmission oils.
Group V
This group includes base oils which are not present in other groups such as naphthenic, esters and polyglycols.
