Virgin Base Oil 6 cSt is a high-performance Group III hydrocracked base oil distinguished by its outstanding oxidation stability, low sulfur content, high viscosity index (above 120), and superior low-temperature fluidity. The "6 cSt" refers to the oil’s kinematic viscosity measured in centistokes (cSt) at elevated temperatures, indicating how easily the oil flows—the higher the cSt, the thicker the oil.

This base oil is produced using an advanced Iso-dewaxing process, which significantly reduces sulfur and aromatic compounds. Although often marketed as partly synthetic or synthetic lubricants in some regions, these oils contain no chemically synthesized components and have over 90% saturates. it has a viscosity of approximately 5.8-6.2 cSt at 100°C.

Because of their low aromatic content, Group III base oils have limited additive solubility but offer superior molecular uniformity, stability, and very low electrical conductivity (under 10 pS/m), reflecting their near non-polar nature. TThese attributes make them well-suited as base stocks for engine oils and advanced industrial lubricants. They are commonly blended with additives and sold as synthetic or semi-synthetic products.
