Marine Diesel Cylinder Oil 70TBN SAE 50

Marine Diesel Cylinder Oil 70TBN SAE 50 is a high-performance cylinder lubricant engineered for low-speed, crosshead marine diesel engines operating on high-sulfur heavy fuel oils (HFOs). Formulated with a Total Base Number (TBN) of 70, this oil provides outstanding acid neutralization, guarding critical engine parts against corrosion and deposit buildup caused by sulfuric acid formation during fuel combustion.

The SAE 50 viscosity ensures a strong oil film under high-pressure, high-temperature operating conditions typical of slow-speed engines. Its robust detergent and dispersant additives help maintain piston cleanliness, reduce ring zone deposits, and prevent liner wear or scuffing over long voyages.

This oil is ideally suited for vessels burning intermediate or high-viscosity fuel oils in deep-sea shipping, especially where extended service intervals and high thermal loads demand top-tier lubricant performance. It is compatible with engines from leading OEMs and aligns with major industry specifications.

Key Benefits:

• High 70 TBN offers excellent protection against acidic corrosion

• Designed specifically for crosshead-type marine diesel engines

• Maintains piston and liner cleanliness under high-load operations

• SAE 50 viscosity ensures film strength and thermal stability

• Reduces scuffing, wear, and deposits for longer engine life

• Supports optimal performance in high-sulfur fuel environments
