Base Oil Group – II
N600

Description:
N600 is a very high-viscosity Group II base oil produced via hydrocracking and severe hydrotreating of high-quality paraffinic crude oil. With its strong film-forming capability, excellent oxidative stability, and low sulfur content, N600 is ideally suited for use in heavy-duty lubricants, industrial gear oils, marine oils, and grease production. Its high viscosity makes it particularly effective in formulations that require enhanced load protection and thermal stability.

Production Process:

  • Hydrocracking / Hydrotreating: Deeply saturates the oil, removing aromatics and sulfur for improved cleanliness and oxidation resistance

  • Isodewaxing: Improves pour point and cold-flow behavior

  • Hydrofinishing: Polishes the oil for color stability, purity, and extended service life

Key Technical Properties (Typical Values):

  • Viscosity @ 100°C: ~14.0–16.5 cSt

  • Viscosity Index (VI): 105–115

  • Flash Point (COC): >250°C

  • Pour Point: -9°C to -15°C

  • Color (ASTM D1500): L0.5–L1.0 (water-clear)

  • Sulfur Content: ≤ 0.03%

  • Saturates: ≥ 90%

  • Oxidation Stability: Excellent under severe thermal conditions

  • Volatility: Low – supports high-temperature performance

Benefits:

  • Superior film strength for protection under heavy load and high temperature

  • Outstanding oxidative and thermal stability for extended lubricant life

  • Low volatility and sulfur content reduce emissions and oil consumption

  • High purity ensures excellent additive solubility and compatibility

  • Ideal for enhancing viscosity in multi-grade lubricant formulations

  • Reliable performance in severe-duty automotive and industrial systems

Applications:

  • Heavy-Duty Engine Oils (HDEO): Blending component for high-viscosity and shear-stable formulations

  • Marine and Railway Oils: For use in large engines operating under extreme mechanical stress

  • Industrial Gear Oils: Where strong film strength and thermal resistance are critical

  • Grease Manufacturing: Base fluid for calcium, lithium, and complex soap greases

  • Metalworking Fluids: High-load cutting and forming oil formulations

  • Process & Blending Base: Used to increase viscosity in multigrade oils or adjust formulation balance

Packaging Options:

  • Available in bulk, 200-liter drums, IBCs (totes), or flexitanks

  • Custom blends and additive packages available upon request

Compliance & Standards:

  • Conforms to API Group II base oil classification

  • Suitable for use in lubricant formulations targeting API SN, SP, and ACEA performance levels, when used with compliant additive systems

  • Fully compatible with Group II+, Group III, and synthetic base oils
