What is Base Oil SN150? | Uses, Properties, and Supplier Guide

In the lubricants and industrial oil markets, Base Oil SN150 plays a critical role. As a light-grade Group I base oil, SN150 is commonly used in formulating a wide variety of automotive and industrial lubricants. Whether you’re a manufacturer, blender, or distributor, understanding what Base Oil SN150 is helps you make informed sourcing decisions.

What is SN150 Base Oil?

SN150 base oil is a Solvent Neutral 150 mineral oil, categorized under Group I base oils. It is produced from refined crude oil and is known for its light viscosity, good solvency, and compatibility with a wide range of additives.

🏭 Production Process of SN150 Lubricant Base Oil

The typical process to manufacture SN150 base oil includes:

• Atmospheric & vacuum distillation

• Solvent extraction

• Dewaxing

• Hydro-finishing or clay filtering

The result is a clear, stable, and low-viscosity SN150 lubricant oil, ideal for use in general-purpose applications.

📊 SN150 Specifications & Technical Properties

These SN150 oil specifications make it ideal for use in low-friction, fuel-efficient lubricant formulations.

SN150 refers to the viscosity grade of the base oil, with “SN” indicating that it is suitable for use in lubricants and “150” representing its kinematic viscosity at 100 degrees Celsius. The kinematic viscosity of SN150 typically ranges from 135 to 165 centistokes (cSt) at this temperature.

Common Applications of SN150 Base Oil

SN150 is used in light-duty and industrial applications such as:

• Automotive engine oils (monograde/multigrade)

• Textile lubricants

• Metalworking fluids

• Hydraulic fluids

• Transformer oils

• Industrial gear and circulation oils

Its excellent fluidity and clean performance make it a top choice for industrial base oil SN150 users.

SN150 is commonly used in applications that require moderate viscosity and lubricating properties. It is suitable for use in industrial and automotive lubricants, including hydraulic fluids, gear oils, metalworking fluids, and general-purpose lubricants.

One of the key advantages of using Base Oil SN150 is its good solvency power, which allows it to effectively dissolve and carry additives in lubricant formulations. This helps enhance the performance of the lubricant by improving its resistance to oxidation, corrosion, and wear.

✅ Benefits of Using SN150 Base Oil

• ✔️ Light viscosity for cold flow & efficiency

• ✔️ Excellent response to additives

• ✔️ Stable and clean-burning

• ✔️ Cost-effective lubricant base stock

• ✔️ Ideal for blending with SN500 or SN650

Additionally, SN150 offers good low-temperature fluidity, ensuring that the lubricant remains effective even in colder environments. It also provides adequate film strength at higher temperatures, reducing friction and protecting machinery from excessive wear and tear.

SN150 is compatible with a wide range of additives, allowing formulators to customize lubricant formulations to meet specific performance requirements. It can be blended with other base oils or additives to achieve desired viscosity grades and enhance performance characteristics.

🔁 SN150 vs SN500 vs SN650: What’s the Difference?

👉 SN150 is best used in low-viscosity formulations or as a blend component with SN500 and SN650 base oils.

When selecting SN150 for a particular application, it is important to consider factors such as the operating conditions, equipment requirements, and lubricant specifications. Consulting with lubricant formulators or experts can help determine the optimal base oil and formulation for the desired performance objectives.

❓ FAQs About SN150 Lubricant Oil

1. What is SN150 used for?

SN150 is used in light-duty lubricants like hydraulic oils, transformer oils, and low-viscosity engine oils.

2. Can SN150 be used as a synthetic oil replacement?

No. SN150 is a Group I mineral oil, not synthetic. It can, however, be blended with synthetic components.

3. What is the difference between SN150 and SN500?

The primary difference is viscosity. SN150 is thinner and flows more easily, while SN500 is thicker and better for medium-duty applications.

4. How do I know if SN150 is the right base oil for me?

If you need a low-viscosity, general-purpose base oil, SN150 is a great fit—especially for low-temperature or energy-efficient applications.

5. Who supplies SN150 globally?

Pars Universal Bitumen is a trusted global supplier of SN150, exporting to markets in Asia, Africa, and Europe.

Conclusion: Why SN150 Base Oil Matters for Lubricant Applications

Base Oil SN150 remains a reliable and cost-effective choice for manufacturers seeking a light-viscosity, Group I mineral oil with good solvency and blend flexibility. Its wide use across automotive, industrial, and electrical applications proves its versatility and performance when formulating general-purpose lubricants.

While newer Group II and Group III offer enhanced purity, SN150 still holds a competitive edge in terms of affordability and compatibility with additive packages—especially in regions where cost-performance balance is essential.
