Base oil SN 500

Base oil SN500 is a medium-viscosity solvent neutral base oil widely used in the production of automotive and industrial lubricants. It offers a strong balance between viscosity, thermal stability, and additive compatibility, which makes it ideal for engine oils, hydraulic fluids, gear oils, and greases. Thanks to its stable performance under pressure and heat, base oil SN500 helps extend equipment life, reduce wear, and maintain smooth operation in demanding conditions. For lubricant manufacturers looking for dependable quality, cost efficiency, and consistent supply, this grade remains one of the most practical choices in the global market.

What Is Base Oil SN500?

Base oil SN500 is a Group I solvent-refined base oil produced from crude oil through controlled refining processes. The “SN” stands for Solvent Neutral, while “500” refers to its viscosity range. This grade typically has a kinematic viscosity of about 28–32 cSt at 40°C, placing it in the medium-viscosity category.

Because of its molecular structure, SN500 offers good solvency, which allows additives to dissolve easily and perform effectively. This feature is especially important for lubricant formulations that require detergents, antioxidants, anti-wear agents, and viscosity improvers.

In simple terms, base oil SN500 acts as the foundation of many lubricants, giving them strength, stability, and long service life.

How Base Oil SN500 Is Produced

Manufacturers produce base oil SN500 through solvent refining, one of the traditional and widely used base oil production methods.

The process includes:

• Atmospheric and vacuum distillation of crude oil

• Solvent extraction to remove unwanted aromatics

• Dewaxing to improve low-temperature behavior

• Finishing steps to improve stability and color

This method creates a base oil with good lubrication properties, reliable viscosity, and acceptable oxidation resistance for many industrial and automotive applications.

Why Base Oil SN500 Is So Widely Used

Base oil SN500 remains popular because it meets three critical needs at the same time:

1. Performance – Stable lubrication under load and heat

2. Flexibility – Works in many lubricant formulations

3. Cost efficiency – More affordable than higher-group base oils

As a result, lubricant blenders often choose SN500 to balance quality and price without sacrificing reliability.

Base Oil SN500 vs Other Base Oil Grades

Understanding how SN500 compares helps buyers choose correctly.

SN150 vs SN500

• BASE OIL SN150 is lighter and flows faster

• SN500 offers stronger film strength and load protection

SN300 vs SN500

• SN300 balances flow and thickness

• SN500 performs better in heavy-duty applications

SN500 vs Group II Base Oils

• Group II oils have lower sulfur and higher purity

• SN500 offers better solvency and lower cost

For many applications, SN500 remains the most practical choice.

Packaging and Supply Options

Suppliers usually offer base oil SN500 in multiple packaging formats:

• Bulk tankers

• Flexitanks

• IBC totes

• 208-liter steel drums

Each shipment typically includes:

• Certificate of Analysis (COA)

• Technical Data Sheet (TDS)

• Material Safety Data Sheet (MSDS)

This ensures quality control and regulatory compliance.

Storage and Handling Guidelines

Proper storage keeps the oil clean and usable.

• Store in a dry, covered area

• Keep containers sealed

• Avoid water and dust contamination

• Protect from direct sunlight

• Use clean transfer equipment

Following these steps preserves oil quality and extends shelf life.
