DaTo Active 600 15W40 Heavy Duty Diesel Engine Oil

DaTo ACTIVE 600 15W40 Heavy Duty Diesel Engine Oil API Cj-4

DaTo ACTIVE 600 15W40 is a high performance heavy duty diesel engine lubricant specially formulated for modern high-speed four-stroke diesel engines operating in extreme commercial and industrial environments. Built using ultra-refined mineral base oils and an advanced heavy-duty additive system, this lubricant provides outstanding engine cleanliness, long service life, superior oxidation resistance, and maximum internal protection.

Designed for commercial fleets, long-haul trucks, buses, construction equipment, mining machinery, agricultural tractors, diesel generators, and off-road heavy-duty applications, DaTo ACTIVE 600 ensures reliable performance even under continuous heavy loads, elevated temperatures, and demanding working cycles.

Its API CI-4 performance level means it is designed to protect engines requiring advanced soot handling, exhaust gas recirculation (EGR) durability, wear resistance, and high temperature oxidation stability for heavy-duty diesel service. API notes that Cj-4 oils were introduced specifically to improve durability in high-speed diesel engines with severe soot loading and EGR systems.

With enhanced anti-wear chemistry, DaTo ACTIVE 600 reduces metal-to-metal friction, protects pistons and turbochargers, minimizes sludge accumulation, and helps extend oil drain intervals—making it the ideal lubricant solution for fleet owners and industrial diesel operators seeking reduced maintenance costs and longer engine life.

• Ultra-Refined Base Oil Technology: Provides superior lubrication film strength, better thermal resistance, and smoother diesel engine operation.
• Advanced Soot & Sludge Control: Keeps contaminants suspended and prevents harmful soot deposits common in EGR-equipped diesel engines.
• Enhanced Wear Protection: Minimizes friction on pistons, liners, bearings, valve trains, and turbocharger components.
• Long Drain Interval Support: Special additive technology helps maintain viscosity and cleanliness for extended oil change periods.
• High Temperature Oxidation Stability: Resists oil breakdown under severe heat, continuous load, and long-distance fleet driving.
• Corrosion & Rust Protection: Protects internal metal components from moisture, acid formation, and oxidation damage.
• Improved Fuel Efficiency: Cleaner combustion and stable lubrication contribute to optimized engine mileage.
• Low Ash Heavy Duty Formulation: Supports turbocharger cleanliness and protects emission-sensitive diesel systems.
• Commercial Grade Diesel Reliability: Perfect for buses, trailers, transport fleets, industrial generators, excavators, tractors, and construction equipment.
