A premium, heavy-duty diesel engine lubricant formulated for the most demanding operating conditions. HD50 is designed with high-viscosity base oils and an advanced additive system to provide maximum protection in large-bore, high-load diesel engines.
Applications
-
Stationary Power Plants: Diesel generator sets in continuous and standby service.
-
Heavy-Duty On-Highway Trucks: Long-haul and vocational vehicles operating under severe duty cycles.
-
Off-Highway Equipment: Construction, mining, and agricultural machinery subjected to high loads and extreme temperatures.
-
Marine Diesel Engines: Auxiliary and propulsion engines requiring robust lubrication.
Key Benefits
-
Superior Wear Protection
Specially formulated anti-wear additives build a resilient film on critical components (bearings, camshafts, pistons), minimizing wear under heavy loads. -
Exceptional Shear Stability
Maintains viscosity and film strength even under high-shear conditions, ensuring consistent lubrication in severe-service engines. -
Enhanced Thermal & Oxidation Stability
Resists oil breakdown, sludge, and varnish formation at high operating temperatures, extending drain intervals and engine cleanliness. -
High HTHS Viscosity
With HTHS ≥3.7 mPa·s, HD50 ensures robust film retention at elevated temperatures and loads, protecting against metal-to-metal contact. -
Acid Neutralization & Cleanliness
Elevated Total Base Number (TBN 10–14 mg KOH/g) neutralizes combustion acids and disperses soot, keeping engine internals free from deposits. -
Cold-Start Performance
The 50 weight grade offers improved pumpability in cooler climates compared to straight 60 or 70 weights, reducing startup wear. -
Corrosion & Rust Inhibition
Inhibitors safeguard engine parts during operation and downtime, particularly in humid or marine environments.
Formulation
-
Base Oils: A blend of selected high-viscosity mineral or synthetic oils chosen for film strength and shear resilience.
-
Additives: A balanced package of detergents, dispersants, anti-wear agents (ZDDP), antioxidants, corrosion inhibitors, defoamants, and pour-point depressants.
Meets or Exceeds

API CI-4 / CH-4 (depending on formulation)
-
ACEA E7 / E9 (European specifications for heavy-duty diesel engines)
-
OEM Approvals: Cummins CES, Caterpillar ECF, MAN M3275, Volvo VDS, and others.
Packaging
