Marine Trunk Piston Engine Oil SAE 30

Description

1. Product Overview
Marine Trunk Piston Engine Oil SAE 30 is a high-performance, mineral-based lubricant engineered specifically for medium-speed trunk piston engines in marine and stationary power generation applications. It delivers superior thermal stability, acid neutralization, and detergency to combat deposits and corrosion from high-sulfur fuels. The value proposition lies in extended drain intervals and reduced cylinder liner wear, offering measurable total cost of ownership (TCO) savings. This product is strategically critical as global fleets demand operational efficiency while complying with stricter emissions and maintenance budgets.

2. Key Specifications & Technical Characteristics

• Chemical composition: High-viscosity index base oil (Group I/II blend) with overbased calcium sulfonate detergents, zinc dialkyldithiophosphate (ZDDP) anti-wear additives, and alkaline reserve (TBN 25–40 mg KOH/g typical)

• Purity level: Additive-free base stock >99% with precision additive package; no water or sediment (<0.05%)

• Physical characteristics: Bright amber liquid; viscosity SAE 30 (12.5–16.3 cSt at 100°C); specific gravity ~0.89–0.91 kg/L; flash point >220°C; pour point -15°C

• Packaging options: 208 L drums, 1,000 L IBC totes, bulk flexitanks (20,000 L), and ISO tank containers

• Shelf life: 36 months in original sealed container under dry, temperate storage

3. Core Industrial Applications

• Primary industries: Deep-sea shipping, coastal tankers, bulk carriers, container vessels, and marine power generation (auxiliary engines)

• Operational use cases: Lubrication of crosshead-type trunk piston engines (e.g., MAN, Wärtsilä, Mitsubishi) burning residual fuels up to 2.5% sulfur; also suitable for medium-speed diesel engines in standby generators

• Performance advantage: Compared to monograde SAE 40 or generic CF oils, this SAE 30 formulation provides faster cold-start circulation, superior soot dispersion, and effective neutralization of sulfuric acid from combustion, reducing ring sticking and cylinder polishing by >30%

• Efficiency benefit: Demonstrated 15–20% longer oil life versus standard marine oils in high-load operation, lowering purchase frequency and disposal costs

4. Competitive Advantages

• Quality consistency: ISO 8217:2024 compliant; batch-tested for TBN retention and viscosity shear stability; zero variation across global supply points

• Supply reliability: Multi-sourced base stocks with 48-hour emergency dispatch from three regional hubs (Rotterdam, Singapore, Houston)

• Logistics capability: Vessel-to-vessel bunkering available; just-in-time delivery to major ports worldwide

• Price competitiveness: Tier-1 additive performance at 8–12% below leading OEM-branded oils for equal TBN spec

• Sustainability & documentation: Lower volatility for reduced oil mist emissions; full declaration of conformity, MSDS, and technical datasheets in 14 languages

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (metric tons)

• Loading capacity per 20 ft container: 20 MT (one full container)

• Loading capacity per 40 ft container: 26 MT (max net weight, subject to axle limits)
