Base Oil Group III 4 cSt

Description

1. Product Overview

Base Oil Group III 4 cSt is a severely hydroprocessed, high-saturation mineral oil with a viscosity of 4 centistokes at 100°C, classified as a high-performance Group III base stock. It is primarily used as the foundational component in advanced engine oils, automatic transmission fluids, and industrial hydraulic oils. The key value proposition is its near-synthetic performance (viscosity index ≥120, low Noack volatility, and high oxidation stability) at a lower cost than PAO synthetics. Strategically, it is critical for lubricant blenders transitioning to ILSAC GF-6, API SP, and ACEA C-series specifications amid tightening emissions and fuel-economy regulations.

2. Key Specifications & Technical Characteristics

• Chemical composition: Severely hydrotreated and hydrocracked base oil; >90% saturates, sulfur <10 ppm

• Purity level / grade: Group III premium grade; Noack volatility ≤13%; Viscosity Index 120–130

• Physical characteristics:

  • Appearance: Clear, bright, and free of sediment

  • Color: <0.5 (ASTM D1500)

  • Density @ 15°C: approx. 820–840 kg/m³

  • Flash point (COC): >210°C

  • Pour point: -15°C to -18°C

• Packaging options: Bulk (ISO tanks, flexitanks), 20L pails, 200L drums, IBC totes (1,000L)

• Shelf life: 36 months when stored in sealed, dry, contaminant-free conditions at ambient temperature

3. Core Industrial Applications

• Primary industries: Automotive lubricants manufacturing, industrial fluids production, metalworking fluids, and specialty grease manufacturing

• Specific use cases:

  • PCMO (passenger car motor oil) for 0W-20, 5W-30 grades

  • Heavy-duty diesel engine oils (API CK-4, FA-4)

  • High-performance hydraulic fluids (ISO VG 32, 46)

  • Transmission and gear oils

• Why better than alternatives: Compared to Group I/II, it halves volatility (cutting oil top-up costs) and doubles oxidation life (extending drain intervals). Versus PAO, it offers near-identical cold-flow performance at 15–25% lower raw material cost.

• Efficiency / cost advantage: Enables formulators to reduce antioxidant additives by up to 30%, lowering finished lubricant cost while achieving Euro VI/EPA emission compliance.

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified plant; each batch GC-MS validated with COA (Certificate of Analysis) within 24 hours of shipment

• Supply reliability: Dedicated Group III production line with 60,000 MT/month capacity; buffer stock in Rotterdam, Houston, and Singapore hubs

• Logistics capability: In-house vessel chartering and rail-loading network reduces lead time variance to <2 days

• Price competitiveness: Fixed quarterly pricing contracts with partial surcharge protection against crude volatility

• Sustainability: Lower carbon footprint than imported Russian/Chinese Group III; available with ISCC+ mass-balance certification for circular or bio-attributed batches

• Technical support: Free blend simulation software access + formulation consulting by PhD-level tribologists

5. Commercial & Supply Information
