Base Oil 6 cSt (Group III)

Description

1. Product Overview

Base Oil 6 cSt (Group III) is a severely hydroprocessed, high-viscosity index (VI) non-conventional base stock, engineered for premium lubricant formulations requiring superior oxidative stability and low-temperature performance. It is primarily used as the foundational fluid in advanced engine oils, automatic transmission fluids (ATF), and industrial hydraulic oils where extended drain intervals are critical. The key value proposition is its ability to bridge the performance gap between conventional Group II oils and costly synthetic Group IV (PAO) alternatives, delivering near-synthetic properties at a competitive price point. Strategically, this product is essential for manufacturers aiming to meet API Group III specifications and evolving global fuel economy standards (e.g., ILSAC GF-6, ACEA C-series).

2. Key Specifications & Technical Characteristics

• Chemical Composition: Severely hydrotreated and hydrocracked mineral oil; >90% saturates; sulfur content <0.03%

• Purity / Grade: Group III, high-purity base oil (Technical Grade)

• Physical Characteristics:

  • Kinematic Viscosity @ 40°C: 28.0 – 32.0 cSt

  • Kinematic Viscosity @ 100°C: 5.8 – 6.2 cSt

  • Viscosity Index (VI): ≥ 125 (ISO 2909)

  • Color: Water white (Saybolt +30 min; < 15 on ASTM D1500)

  • Density @ 15°C: 0.82 – 0.84 kg/l

  • Pour Point: -12°C to -18°C (depending on additive-free state)

  • Volatility (Noack): < 12%

• Packaging Options: Bulk vessel (flexi-bags in containers), ISO tanks, 1000L IBC totes, new 208L steel drums (upon request)

• Shelf Life: 36 months when stored in sealed, moisture-free, clean dry conditions between 5°C – 40°C

3. Core Industrial Applications

• Primary Industries: Automotive lubricants (passenger car motor oil), heavy-duty diesel (HDDO), industrial circulating oils.

• Specific Operational Use Cases:

  • Low-SAPS Engine Oils: Enables full SAPS formulations for diesel particulate filter (DPF) equipped trucks.

  • High-Performance Hydraulics: Reduces sludge formation in high-pressure vane and piston pumps operating at 250–400 bar.

  • Automatic & CVT Fluids: Provides shear stability and stable film thickness across extreme temperature ranges (-30°C to 150°C).

• Performance Advantage: Compared to Group II, this 6 cSt oil reduces low-temperature cranking viscosity (CCS) by up to 35% while cutting evaporative loss (Noack) below 12%, directly extending drain intervals by 30–50% in mixed-fleet operations. Versus PAO, it offers comparable thermal stability at 20–30% lower raw material cost.

4. Competitive Advantages

• Quality Consistency: Lot-to-lot viscosity variation maintained within ±0.1 cSt @ 100°C; ISO 9001:2023 certified quality management with QC data provided per shipment.

• Supply Reliability: Exclusive refining agreement with a Tier-1 Group III producer (South Korea / Middle East origin), guaranteeing 12-month contract stability with no force majeure history in the past 36 months.

• Logistics Capability: Dedicated deep-sea vessel liftings; expedited 10-day delivery to major ports (Houston, Rotterdam, Shanghai, Jebel Ali) via bonded storage hubs.

• Price Competitiveness: Direct mill-to-market model eliminates 2–3 intermediary margins; price locked quarterly for contract volumes >500MT.

• Sustainability: Low polycyclic aromatic (PCA) content (<1%) supports reduced carcinogenic residue in waste oil; compatible with closed-loop re-refining systems.

• Technical Support: On-call tribologist support for formulation adjustments; COA (Certificate of Analysis), SDS, and formulation compatibility guides available in 6 languages.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): Bulk 20MT (flexi-bag or ISO tank equivalent)

• Loading Capacity: 20 MT per 20-ft container (flexi-bag); 24 MT per ISO tank container; max 21.5 MT per standard 20-ft dry van with drummed goods
