Base Oil

BASE OIL GROUP 1

Group I base oils are derived from the extraction and refining of paraffinic crude oil. At room temperature, these oils remain in liquid form and can range in color from white to dark brown. Classified as non-hazardous, Group I base oils are currently among the most cost-effective on the market, suitable for a variety of applications. For specific needs, you can review the specifications of Aumarihant Resources' Group I base oils.

Group I oils are produced through solvent extraction and dewaxing techniques. The process begins with vacuum gas oil, a heavy feedstock from crude distillation. A selective solvent removes sulfur, aromatic, and nitrogen compounds. The resulting oil stream, still containing paraffin, undergoes further treatment. A light solvent is added, and the mixture is chilled to precipitate paraffin, which is then filtered out to create the base oil.

Group I base oils contain more than 0.03% sulfur, less than 90% saturates, and have a viscosity index of 80-119. Their kinematic viscosity and flashpoints are higher, with colors typically light straw, except for the darker bright stock.

Despite variations in crude oil feedstocks, Group I base oils from different refiners generally share similar physical and chemical properties across comparable viscosity grades.

These base oils are commonly transported in ISO tanks, flexitanks, and trucks, and stored in flexitanks. They are widely used in industrial and marine lubricants, as well as in engine oils for older engines.

BASE OIL GROUP II

Group 2 base oil is a mineral base oil created by hydrocracking crude petroleum oil. It has a reduced viscosity, a higher saturation (more than 90 percent saturates), and a lower sulphur concentration (above 0.03 percent). Group II base oils are purer and transparent water-white colours. This grade's viscosity index is frequently more than 100.

Group II base oils are utilised in a variety of lubrication applications and may be used to make almost any lubricant.

Base oils in Group II have superior antioxidative capabilities and a more translucent colour than base oils in Group I. Group II is now utilised more frequently than other grades.

Base oils from Group II are transported in trucks, Flexi-containers, and rail tank cars. You can contact us for Group 2 base oil specs; our sales staff will assist you in selecting the product that is most suited to your needs.

BASE OIL GROUP III

Group III base oils, known for their purity, are produced through hydrocracking, hydroisomerization, and hydrotreating processes. Also referred to as VHVI-4 (Very High Viscosity Index) or synthetic oils, they contain over 90% saturates, less than 0.3% sulfur, and have a viscosity index exceeding 120. These oils feature a water-white appearance and offer excellent low-temperature performance. For more details, please refer to our product specifications.

Group III base oils are primarily used in high-performance engine oils, driveline fluids, and industrial lubricants, serving sectors such as construction, lubrication, and chemicals.

We can supply Group III 4 CST base oils via trucks, flexi-containers, and rail tank cars.
