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
