Petromin Fleet Master Plus SAE 15W-40 18L lubricates heavy-duty diesel engines under high thermal stress. With an API CI-4/SL rating, it prevents deposit buildup in mixed fleets. A 140 viscosity index maintains oil film thickness despite high road dust and heat.
Key Features
- Acid Neutralization: 10.7 mg KOH/g TBN prevents corrosive wear on metal. It extends the functional life of heavy-duty engine components.
- Thermal Stability: 232°C flash point stops oil evaporation under high loads. It reduces the frequency of top-ups during long hauls.
- Soot Handling: 15.1 cSt kinematic viscosity at 100°C resists oil thinning. It prevents sludge formation in high-mileage diesel engines.
- Cold Start Flow: -30°C pour point keeps the lubricant fluid in low temperatures. It prevents dry metal contact during early morning startups.
- OEM Compatibility: MB 228.3 and Cummins CES20077 certifications verify performance. It meets strict manufacturer requirements for heavy machinery.
