Base Oil Group – IV

PAO 4cSt

Description:
PAO 4 cSt is a low-viscosity synthetic base oil from the Group IV (Polyalphaolefin) family, manufactured through the oligomerization of 1-decene, a linear alpha-olefin. Engineered at the molecular level, PAO 4 delivers exceptional oxidation stability, very high viscosity index, and outstanding low-temperature performance, making it the ideal choice for fuel-efficient synthetic lubricants used in automotive, industrial, and specialty applications. It provides the thermal durability and performance consistency required in demanding operating conditions.

Production Process:

• Oligomerization of Alpha-Olefins: Forms uniform synthetic hydrocarbon chains
• Hydrogenation: Fully saturates the structure, eliminating double bonds and sulfur
• Fractionation: Produces narrow-cut viscosity grades for precise formulation control

Key Technical Properties (Typical Values):

• Kinematic Viscosity @ 100°C: ~3.9–4.1 cSt
• Kinematic Viscosity @ 40°C: ~18–20 cSt
• Viscosity Index (VI): ~130–140
• Flash Point (COC): >230°C
• Pour Point: -60°C or lower
• Volatility (NOACK): Extremely low
• Color: Water-clear
• Saturates: ~100%
• Sulfur Content: 0%
• Shear Stability: Excellent – maintains viscosity under stress

Benefits:

• Ideal for formulating low-viscosity, energy-efficient engine oils
• Outstanding cold-temperature flow – ensures rapid lubrication during cold starts
• Very high thermal and oxidative stability – supports extended drain intervals
• Ultra-low volatility – minimizes oil consumption and tailpipe emissions
• Compatible with a wide range of additives, esters, and other base stocks
• Water-clear and chemically inert – ideal for high-purity applications

Applications:

• Passenger Car Motor Oils (PCMO): Synthetic formulations such as SAE 0W-20, 5W-20, and 0W-30
• Heavy-Duty Engine Oils (HDEO): High-performance diesel oils for long-drain intervals
• Gear & Transmission Fluids: Where shear stability and thermal control are critical
• Compressor Oils & Hydraulic Fluids: Premium synthetic systems requiring clean and stable fluids
• Blending Component: Commonly used to reduce viscosity and improve VI in synthetic lubricant formulations
• Grease Manufacturing: High-purity base for low-viscosity synthetic greases

Packaging Options:

• Available in bulk, 200-liter drums, IBCs (totes), or flexitanks
• Custom packaging and blend optimization support available

Compliance & Standards:

• Fully meets API Group IV (PAO) base oil specifications
• Suitable for lubricants targeting API SN/SP, ILSAC GF-6/7, ACEA, and leading OEM approvals
• Fully compatible with Group III, Group V, esters, and advanced additive systems
