Types of Base Oil

Explore our comprehensive portfolio of N-Series and Solvent Neutral (SN-Series) base oil grades, offering tailored viscosity ranges, superior oxidation stability, and versatile blending capabilities for industrial formulations and lubricant manufacturing.

01

N-60 2 cSt Oil

N-60 2 cSt oil is a light-viscosity base oil grade, with the stated 2 cSt indicating a viscosity of two centistokes at a specified test temperature. Such light oils are used in specialised lubricant formulations and industrial applications requiring easy flow and rapid heat dissipation.

Light-Viscosity • 2 cSt Ultra-Fluid
02

N-70 Base Oil

N-70 base oil is a relatively light base oil commonly associated with Group II base stocks. It offers suitable fluidity for blending lighter lubricants and industrial oils. Its performance depends on viscosity, oxidation stability, volatility and purity, reporting approximately 10.9–13.6 cSt viscosity at 40°C.

Group II Stock • 10.9–13.6 cSt @ 40°C
03

N-150 32 cSt Oil

N-150 base oil is a medium-viscosity base stock, typically having a kinematic viscosity of approximately 28–32 cSt at 40°C. It is used in manufacturing hydraulic oils, industrial lubricants, circulating oils and other lubricant formulations requiring moderate fluidity and lubrication performance.

Medium Viscosity • 28–32 cSt @ 40°C
04

N-500 Base Oil (White)

N-500 white base oil is a relatively high-viscosity base stock with a light or nearly colourless appearance, depending on the supplier's specifications. It can be used as a blending component in industrial lubricants and other formulations requiring greater viscosity and high thermal stability.

White Stock • High-Viscosity Grade
05

N-600 Base Oil (White)

N-600 white base oil is generally marketed as a heavier base oil grade with a pale or nearly colourless appearance. It is selected for lubricant formulations that require higher viscosity, robust film-forming properties, high flash point safety, and elevated oxidation stability.

Heavy White Grade • Film-Forming
06

SN-150 32 cSt (Yellow)

SN-150, meaning Solvent Neutral 150, is a mineral base oil commonly produced through solvent refining and finishing processes. Its typical viscosity is approximately 28–32 cSt at 40°C. It is widely used in hydraulic oils, industrial lubricants and multi-grade lubricant blends.

Solvent Neutral • 28–32 cSt @ 40°C
07

SN-300 Base Oil (Yellow)

SN-300 is a medium-viscosity solvent-neutral mineral base oil used in lubricant manufacturing. It is generally heavier than SN-150 and lighter than SN-500, with viscosity typically 50–70 cSt at 40°C. It is ideal for industrial lubricant blends and circulating systems requiring intermediate viscosity.

Intermediate • 50–70 cSt @ 40°C
08

SN-400 Base Oil (Yellow)

SN-400 base oil is a commercial solvent-neutral grade that generally falls between SN-300 and SN-500 in viscosity. It is used as a blending component for industrial lubricants and other petroleum-based products requiring moderate-to-high viscosity and shear resistance.

Moderate-to-High Viscosity Grade
09

SN-500 Base Oil (Yellow)

SN-500 is a relatively heavy solvent-neutral mineral base oil used in producing industrial lubricants, gear oils and higher-viscosity formulations. Its typical kinematic viscosity is approximately 90–110 cSt at 40°C with excellent flash point safety and oxidation stability.

Heavy Neutral • 90–110 cSt @ 40°C
