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.
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.
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:
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.
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
