Base Oil Group – II
N500

Description:
N500 is a high-viscosity Group II base oil, produced via hydrocracking and hydrotreating of high-quality paraffinic crude. With its high viscosity, low sulfur content, and excellent thermal stability, N500 is ideal for use in the formulation of heavy-duty engine oils, gear oils, greases, and industrial lubricants. Its high purity and oxidative resistance make it a reliable base stock for applications that demand long service life and robust performance under stress and heat.

Production Process:

  • Hydrocracking / Hydrotreating: Removes sulfur and aromatics, producing a highly saturated and stable base oil

  • Isodewaxing: Enhances cold flow performance and reduces pour point

  • Hydrofinishing: Ensures color stability, clarity, and resistance to degradation

Key Technical Properties (Typical Values):

  • Viscosity @ 100°C: ~10.5–11.5 cSt

  • Viscosity Index (VI): 105–120

  • Flash Point (COC): >240°C

  • Pour Point: -12°C to -18°C

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

  • Sulfur Content: ≤ 0.03%

  • Saturates: ≥ 90%

  • Oxidation Stability: Excellent

  • Volatility: Low – supports high-temperature stability and low oil consumption

Benefits:

  • Excellent thermal and oxidative stability for heavy-duty applications

  • Superior film strength and lubricating performance under load

  • Low volatility and high viscosity for better wear protection

  • High purity improves additive solubility and system cleanliness

  • Consistent quality and performance for demanding industrial and automotive use

  • Longer lubricant life and fewer maintenance intervals

Applications:

  • Heavy-Duty Engine Oils (HDEO): Ideal for high-viscosity diesel and gas engine formulations

  • Gear Oils: Automotive and industrial gear oils requiring shear stability and thermal resistance

  • Grease Manufacturing: High-purity base for lithium, calcium, and complex soap greases

  • Industrial Lubricants: Circulation oils, hydraulic systems, compressors, and turbines

  • Marine & Railroad: Lubricants for systems operating under high mechanical and thermal stress

  • Metalworking: Suitable for blending with other base stocks for high-load cutting oils

Packaging Options:

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

  • Available with custom blend ratios and additive pre-mixes on request

Compliance & Standards:

  • Meets all criteria for API Group II base oil classification

  • Suitable for lubricant formulations that meet API SN, SP, and ACEA performance levels when used with approved additive packages

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