6cSt Base Oil

6cSt Base Oil
6cSt base oil is a medium-viscosity base oil (approximately 6 centistokes at 100°C), typically classified under Group II or Group III base oils. Due to its enhanced properties and high performance, it is widely used in the formulation of advanced lubricants and various industrial applications. With balanced viscosity, 6cSt base oil is well-suited for applications requiring effective lubrication, thermal stability, and proper fluidity across a wide temperature range. It is available in two variants: 6cSt Soil Korea and 6cSt ADNOC, produced by leading global manufacturers—Soil Korea from South Korea and the Abu Dhabi National Oil Company (ADNOC) from the United Arab Emirates.

6cSt Soil Korea is manufactured using advanced hydrocracking and isomerization processes, resulting in high purity, extremely low sulfur content (less than 0.03%), and a high viscosity index (typically between 120 and 130). These characteristics make it suitable for high-performance automotive and industrial lubricants, such as hydraulic and engine oils. 6cSt ADNOC is also produced using modern refining technologies, including hydrogenation, and is recognized globally for its excellent oxidation stability, light color, and reliable performance under harsh conditions. Both variants comply with international standards such as API and ASTM.

Group II and III base oils, like 6cSt, offer better chemical and thermal stability compared to Group I oils (such as SN500) due to their more advanced refining processes. Derived from crude oil, these oils are refined through hydrocracking to remove undesirable compounds like aromatics and sulfur, resulting in superior performance. 6cSt base oil typically makes up 70% to 95% of a lubricant formulation, with additives included to enhance specific properties like wear resistance or high-temperature stability.

Applications
6cSt base oil is used as a foundation for producing various lubricants and industrial products, including:

• Medium-viscosity engine oils (e.g., 5W-30, 10W-40)

• Industrial hydraulic oils

• Automatic transmission fluids (ATF)

• Industrial gear oils

• Compressor lubricants

• Transformer oils

• Metalworking fluids

Advantages of 6cSt Base Oil

• Thermal and Oxidation Stability: Excellent resistance to degradation at high temperatures.

• High Purity: Very low sulfur and aromatic content, especially in Soil Korea and ADNOC variants.

• High Viscosity Index: Maintains fluidity and effective lubrication across temperature ranges.

• Low Volatility: Reduces oil loss and increases lubricant service life.

• Bright and Clear Appearance: Suitable for applications where product appearance matters.

• High Flash Point: Enhanced safety in high-temperature applications.

• Additive Compatibility: Excellent solvency for advanced formulations.

• Environmental Performance: Low sulfur content reduces environmental impact.

Viscosity Analysis
With a viscosity of 6cSt at 100°C, this oil is classified as medium-viscosity, suitable for applications requiring a balance between fluidity and lubricating film strength. Its high viscosity index (typically 120–130) ensures that it remains fluid at low temperatures while maintaining stability at high temperatures, making it ideal for high-performance industrial equipment and modern engines.
