SN150 Base Oil Specification, Production Process & Industrial Applications

What Is SN150 Base Oil?

SN150 Base Oil is a Group I mineral base oil derived from crude oil through solvent refining.
It is classified as a light-to-medium viscosity base stock, widely used as a raw material in the production of lubricants, industrial oils, and greases.

The abbreviation SN stands for Solvent Neutral, indicating that the oil has been refined using solvent extraction to remove unstable aromatic compounds.
The number 150 refers to its viscosity range, placing SN150 between lighter grades such as SN100 and heavier grades like SN300 or SN500.

How SN150 Base Oil Is Produced

The manufacturing process of SN150 Base Oil follows traditional refining steps used for Group I base oils:

1. Crude Oil Distillation
   Crude oil is separated into different fractions through atmospheric and vacuum distillation.

2. Lubricating Oil Cut Selection
   A specific heavy fraction suitable for lubricant production is selected.

3. Solvent Refining
   Selective solvents remove aromatics and impurities, improving oxidation stability and clarity.

4. Dewaxing
   Wax content is reduced to enhance low-temperature performance and flow behavior.

5. Hydro Finishing
   Final treatment improves color, odor, and overall chemical stability.

6. Viscosity Classification
   The refined base stock is classified as base oil 150 based on viscosity characteristics.

Applications of SN150 Base Oil

SN150 Base Oil is selected for applications where balanced viscosity, stable flow, and cost efficiency are required.

Common applications include:

• Lubricant manufacturing

• Light engine oils

• Industrial oils

• Hydraulic oils

• Grease formulations

• General-purpose and metalworking fluids

Its moderate viscosity allows smooth circulation while maintaining sufficient film strength for everyday industrial use.

SN150 vs Other SN Grades

SN150 vs SN100

• SN100 is lighter and flows faster

• SN150 provides better film strength and control

SN150 vs SN300 / SN500

• SN300 and SN500 are thicker and suitable for high-load or high-temperature conditions

• SN150 offers improved flow, cleaner appearance, and easier blending

Overall, base oil 150 is considered one of the most versatile base oil grades, suitable for multi-purpose lubricant formulations.

Advantages of SN150 Base Oil

• Balanced viscosity for stable system performance

• Good compatibility with common additive packages

• Cleaner color compared to heavier SN grades

• Improved low-temperature behavior

• Economical choice for large-scale production

These characteristics make base oil a widely used base stock across lubricant industries worldwide.
