Base Oil SN150 Definition
Base Oil SN150 is a mid-range viscosity base oil used in the formulation of lubricants. The “SN” stands for “solvent neutral,” indicating that the oil has been refined through solvent extraction to remove impurities and improve its properties. The “150” denotes its viscosity grade, typically around 150 centistokes (cSt) at 40°C.
Key Characteristics of SN150
- Viscosity: It has a viscosity of approximately 150 cSt at 40°C, making it suitable for applications requiring medium lubrication.
- Purity: Solvent extraction results in a high level of purity, with low levels of sulfur, aromatics, and other impurities.
- Performance: It offers good oxidation stability, thermal stability, and moderate volatility, making it effective in a range of operating conditions.
- Applications: Commonly used in manufacturing automotive lubricants, industrial oils, hydraulic fluids, and other lubricants requiring medium viscosity.
Typical Properties of Base Oil SN150
- Viscosity Index (VI): Typically around 95-105, indicating stability over a wide temperature range.
- Pour Point: Usually around -12°C to -9°C, reflecting the temperature below which the oil ceases to flow.
- Flash Point: Generally around 200°C to 230°C, indicating the temperature at which the oil vapor can ignite.
Uses of Base Oil SN150
- Engine Oils: As a base for blending with additives to produce engine oils.
- Industrial Lubricants: Used in machinery requiring medium lubrication.
- Hydraulic Fluids: Suitable for hydraulic systems operating in moderate conditions.
- Gear Oils: Utilized in the formulation of gear oils needing medium viscosity.
Benefits:
- Versatility: Suitable for a wide range of applications due to its balanced viscosity.
- Purity: Low impurity levels enhance performance and longevity.
- Stability: Good thermal and oxidation stability ensure consistent performance over time.
Base Oil SN150 is an essential component in many lubricant formulations, known for its balance of properties that make it versatile and reliable for various industrial and automotive applications.

Packing of Base Oil:
Base oil packed in new or used 180 kg drums, iso tank, flexitanks, and bulk shipments. Each 20-foot container takes 80 drums.
