Base Oil Group – III

3cSt

Description:
Group III – 3 cSt is an ultra-light, high-purity base oil produced through severe hydrocracking and hydroisomerization of paraffinic crude. With its very low viscosity, extremely high viscosity index, and exceptional oxidative stability, this base stock is ideal for formulating fuel-efficient, low-viscosity lubricants. Its purity, low volatility, and excellent cold flow behavior make it an essential component in next-generation passenger car motor oils, particularly those meeting the latest API SP, ILSAC GF-6/7, and OEM fuel economy specifications.

Production Process:

• Severe Hydrocracking & Hydroisomerization: Removes impurities and restructures molecules for optimal thermal and oxidative stability

• Hydrofinishing: Enhances clarity, stability, and performance consistency

• High-Pressure Fractionation: Ensures precise viscosity control for ultra-light cuts

Key Technical Properties (Typical Values):

• Kinematic Viscosity @ 100°C: ~3.0–3.4 cSt

• Viscosity Index (VI): ≥ 120 (often 125–135)

• Flash Point (COC): >190°C

• Pour Point: -24°C to -30°C

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

• Sulfur Content: ≤ 0.03%

• Saturates: ≥ 90%

• Oxidation Stability: Outstanding

• Volatility (NOACK): Very low – supports fuel economy and low oil consumption

Benefits:

• Enables formulation of low-viscosity SAE grades such as 0W-16, 0W-20, and 5W-20

• Improves fuel economy through reduced internal friction and lighter viscosity

• Excellent oxidative and thermal stability for extended oil life

• Outstanding cold temperature performance for reliable cold starts

• Low volatility reduces oil consumption and emissions

• Water-clear and highly consistent – ideal for precision blending and advanced formulations

Applications:

• Passenger Car Motor Oils (PCMO): Especially for modern gasoline and hybrid engines requiring ultra-low viscosity oils

• Synthetic Engine Oil Blends: Used as a key component in full-synthetic and synthetic technology lubricants

• Transmission Fluids: Where low viscosity and thermal stability are critical

• Hydraulic and Circulating Oils: For systems operating in cold environments or requiring thin-film lubrication

• Fuel Economy Oils: Engine oils designed to meet or exceed API SP, ILSAC GF-6A/B, and future GF-7 standards

Packaging Options:

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

• Custom packaging and blending support available on request

Compliance & Standards:

• Fully meets API Group III base oil specifications

• Suitable for use in formulations designed to meet API SP, ILSAC GF-6A/B, ACEA C5, and various OEM fuel efficiency standards

• Compatible with Group III+, PAO, and synthetic esters for advanced performance blending
