Base Oil 8 cSt (Group III)

Description

1. Product Overview

Base Oil 8 cSt (Group III) is a premium, severely hydroprocessed mineral base oil derived from high-saturation index crude fractions, exhibiting a viscosity index ≥120 and pour point ≤ -12°C. It is the strategic choice for formulating high-performance passenger car motor oils (PCMOs), heavy-duty diesel engine oils (HDDOs), and energy-efficient industrial circulating fluids. The value proposition lies in exceptional oxidative stability, low Noack volatility, and robust film strength under extreme shear. As global regulations tighten toward low-SAPS and fuel-efficient lubricants, Group III base oil serves as the cost-effective, scalable bridge between conventional Group II and full synthetics.

2. Key Specifications & Technical Characteristics

• Chemical composition: Severely hydrotreated mineral oil (Group III), saturates content ≥90%, sulfur ≤0.03%

• Purity level: High-purity industrial grade, free of additives, PCBs, and halogenated compounds

• Physical characteristics: Clear, bright liquid; typical kinematic viscosity 7.8–8.2 cSt @ 100°C; viscosity index (VI) 120–130; pour point –12°C to –15°C; flash point (COC) ≥220°C; density ~0.84 g/cm³ @ 15°C

• Packaging options: Bulk (ISO tank, flexitank, road tanker), drums (new 200L steel drums), IBC totes (1,000L)

• Shelf life: 36 months in sealed, moisture-free conditions; storage temperature 5–40°C

3. Core Industrial Applications

• Automotive lubricants: Primary base for API SP, ILSAC GF-6, and ACEA C3/E4 engine oils – reduces high-temperature deposits and cold-start wear vs. Group II.

• Industrial hydraulics: High-VI hydraulic fluids (HLP/HVLP) for mobile equipment operating in variable climates – delivers 20% longer pump life under thermal cycling.

• Compressor & gear oils: Rotary screw compressor fluids and synthetic-blend gear oils – lowers foaming and energy loss due to reduced friction coefficient.

• Metalworking fluids: Base for low-oil-mist, high-lubricity circulating oils – outperforms Group I in oxidation stability, reducing sump sludge by 40–50%.

4. Competitive Advantages

• Quality consistency: ISO 9001:2015 and API Group III certification with batch-to-batch VI variance ≤2 units.

• Supply reliability: Multiple source-certified refineries (East Asia & Middle East) with 99% on-time delivery rate for spot and contract volumes.

• Logistics capability: Global hub storage (Rotterdam, Houston, Shanghai, Jebel Ali) enabling ≤10-day lead times to major industrial zones.

• Price competitiveness: 12–18% lower cost per VI point than PAO, with comparable Noack volatility.

• Sustainability: Lower carbon footprint vs. Group II (severer hydrotreating recovers >99% of feedstock); supports finished lubricant formulators in meeting EcoLabel and CO₂ reduction targets.

• Technical support: Full product data sheets (PDS), safety data sheets (SDS), and blend compatibility matrices with common additives (ZDDP, MoDTC, aminic antioxidants).

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (bulk) or 80 drums (200L)

• Loading capacity: 20 MT per 20-ft container (flexitank or drum stack) / 1 ISO tank container = 24 MT net
