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
