Forklift loading red drums of BASEOIL SN 650 into a shipping container at Basekim’s warehouse.

BASE OIL SN650 is a high-viscosity, solvent neutral base oil widely used in industrial lubricants, automotive engine oils, and grease production. Because it offers strong thermal stability, excellent lubrication, and reliable film strength, this grade plays a major role in formulating oils designed for extreme pressure and high temperature conditions. Moreover, manufacturers choose BASE OIL SN650 from Basekim when durability, load-carrying ability, and long service life are essential.

What Is BASE OIL SN650?

Simply put, BASE OIL SN650 is a Group I petroleum derived base oil with a higher viscosity index than lighter grades such as base oil SN150 or SN500. Its typical kinematic viscosity of 11–13 cSt at 100°C makes it suitable for thick, heavy duty lubricants. Additionally, it offers:

  • A flash point above 240°C

  • Strong oxidation resistance

  • Reduced volatility

  • Enhanced shear stability

Because of these qualities, heavy machinery, marine engines, and diesel powertrains rely on SN650 for consistent lubrication under stress.

Major Applications of BASE OIL SN650

Thanks to its balanced composition and dependable viscosity, SN650 supports a wide range of industrial and automotive formulations. For example, it is commonly used in:

Most Common Uses

  • Automotive Engine Oils: Base component in multigrade lubricants

  • Industrial Gear Oils: Provides high load bearing performance

  • Greases: Acts as a thick, stable base for heavy load applications

  • Diesel Engine Oils: Withstands high pressure and thermal shock

  • Hydraulic Fluids: Delivers stable flow in high demand systems

Because SN650 adapts well to different additive packages, it remains a preferred choice for cost-effective and high-performance lubrication systems around the world.

Key Technical Features and Advantages

Choosing the right base oil directly affects machinery longevity. SN650 offers high performance in both cold and hot operating conditions. It maintains a strong lubrication film, protects metal parts from wear, and improves overall equipment efficiency.

Key Benefits

  • High viscosity index for excellent film strength

  • Superior oxidation and thermal stability

  • Lower volatility, reducing the need for top-ups

  • Works with various additive packages

  • Longer service life and reduced maintenance costs

As a result, companies achieve improved reliability and operational savings across their machinery fleet.

Grades, Packaging & Quality Control

BASE OIL SN650 is typically supplied in technical grade after refining processes that remove aromatics, sulfur, and other impurities. Because purity matters in lubricant production, quality control labs test every batch for viscosity, flash point, pour point, and color index.

Packaging Options

  • Bulk ISO tanks

  • Flexi tanks

  • 208L steel drums

  • IBC tanks

  • Custom packaging available on request

Each shipment from Basekim undergoes strict QC procedures based on ASTM and DIN standards, ensuring consistent results in every application.
