Description

1. Product Overview

Base Oil Group II 500N is a high-viscosity, hydroprocessed mineral oil with >90% saturates and low sulfur content, engineered for premium lubricant production. It is primarily used in heavy-duty engine oils, industrial gear oils, and hydraulic fluids where thermal stability and oxidation resistance are critical. The key value proposition is its ability to deliver performance near Group III levels at a competitive Group II price point, enabling formulators to meet modern API and ACEA standards efficiently. Strategically, it bridges the gap between cost-driven commodity base oils and high-performance specialty fluids, making it indispensable for lubricant blenders targeting mid-to-heavy duty segments.

2. Key Specifications & Technical Characteristics

• Chemical composition: Hydroprocessed mineral oil, >90% saturates, <0.03% sulfur

• Purity level: API Group II, >99% base oil content

• Physical characteristics: Clear bright liquid; viscosity 95–105 cSt @ 40°C; viscosity index 95–105; flash point (COC) >240°C; pour point -9°C to -12°C

• Density: 0.86–0.88 g/cm³ @ 15°C

3. Core Industrial Applications

• Primary industries: Automotive lubricants, industrial manufacturing, power generation, marine engineering

• Heavy-duty diesel engine oils (CI-4, CJ-4, CK-4): Provides superior soot dispersal and oxidation control compared to Group I, extending drain intervals by 30–40%

• Industrial gear oils: Reduces friction and deposits under high-load, low-speed conditions, outperforming Group I in thermal stability by >50%

• Hydraulic fluids (high-pressure systems): Maintains viscosity shear stability better than lower-viscosity Group II oils, reducing pump wear and leakage

• Cost advantage: Enables blenders to replace up to 30% of Group III in formulations without sacrificing field performance, lowering raw material costs by 10–15%

4. Competitive Advantages

• Quality consistency: ISO 9001-certified refining with real-time GC-MS monitoring; lot-to-lot viscosity variation <2%

• Supply reliability: Dedicated pipeline and tank farm integration with major refineries; 99.5% on-time delivery track record

• Logistics capability: Multi-port warehousing (Houston, Rotterdam, Singapore, Jebel Ali) enabling 7-day average lead time to key industrial zones

• Price competitiveness: Direct refinery offtake agreements remove 2–3 intermediary margins; pricing indexed to Platts with volume-based rebates

• Sustainability: Low sulfur and aromatic content reduce CO₂ footprint in end-use combustion; compatible with re-refining loops

• Technical support: Full Product Data Sheets (PDS), Safety Data Sheets (SDS), and formulation compatibility guides available via API portal

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): Bulk 20 metric tons (MT)

• Loading capacity: 20–24 MT per 20-foot container (flexitank) or 40–45 MT per ISO tank container
