BASE OIL SN650 is a high-viscosity, solvent neutral base oil widely used in the production of industrial lubricants, automotive engine oils, and greases. Because of its excellent thermal stability and strong lubricating properties, it plays a key role in formulating oils that perform under high pressure and extreme temperature.
Moreover, manufacturers prefer BASE OIL SN650 when durability and shear resistance are non-negotiable. Whether it’s gear oil, hydraulic fluids, or marine lubricants, this base oil ensures consistent results.
To put it simply, BASE OIL SN650 is a Group I base oil refined from petroleum crude oil. It has a higher viscosity index compared to SN 150 or SN 500, making it ideal for thick, heavy-duty lubricants. Typically, this base oil has a kinematic viscosity of around 11-13 cSt at 100°C and a flash point exceeding 240°C.
In other words, it offers excellent oxidation resistance, reduced volatility, and enhanced load-carrying ability. That’s exactly why heavy machinery and diesel engines often rely on it.
Thanks to its stable composition, BASE OIL SN650 is used across a wide spectrum of industries. For instance, it’s a favorite for gear oils, transmission oils, and grease formulations.
Most Common Uses:
Automotive Oils: Base component in multigrade engine oils
Industrial Lubricants: Ensures high performance in gearboxes
Greases: Thickening agent for heavy-load applications
Diesel Engine Oils: Withstands high pressure and heat
Hydraulic Fluids: Suitable for systems requiring high load capacity
Because of these diverse applications, it remains one of the most demanded heavy base oils worldwide.
Choosing the right base oil is crucial. SN650 delivers high performance in both cold and hot conditions. Not only does it maintain film strength, but it also protects engine and machine parts from wear and tear.
Key Benefits:
High viscosity index for better film strength
Excellent oxidation and thermal stability
Reduced volatility means fewer oil top-ups
Compatible with various additive packages
Long service life and energy efficiency
Therefore, it reduces maintenance costs while extending machinery lifespan.
BASE OIL SN650 is typically available in technical grade. It is refined to remove aromatics, sulfur, and impurities, which enhances its purity and usability in multiple formulations.
Packaging Options:
Bulk ISO tanks
Flexi tanks
Steel drums (208L)
IBC tanks
