Technical Excellence

Key Features & Operational Benefits

Excellent Detergency & Dispersancy

Effectively cleans soot and combustion deposits, preventing ring sticking and keeping piston underskirts clean.

Good Water Shedding Property

Superior demulsibility properties ensure rapid separation from water contamination in marine operating environments.

Superior Oxidation & Thermal Stability

Resists thermal degradation and oil thickening under high continuous operating loads in marine engine crankcases.

Acid Neutralization & Corrosion Control

TBN 12 alkalinity reserve neutralizes acidic combustion by-products, protecting bearings and liners from corrosive wear.

Frictional Wear Protection

Forms a durable lubricating film on cylinder walls and journal bearings to minimize frictional wear during heavy service.

Prolongs Overall Engine Life

Comprehensive deposit control and anti-wear protection extend overhaul intervals and lower vessel maintenance overhead.
