Marine Diesel Trunk Piston Oil 15TBN SAE 30

Marine Diesel Trunk Piston Oil 15TBN SAE 30 is specially formulated for medium-speed trunk piston diesel engines operating on residual or distillate fuels with moderate to high sulfur content. With a Total Base Number (TBN) of 15, this oil offers a balanced level of alkalinity reserve, effectively neutralizing acidic by-products of combustion to prevent corrosion and extend engine life.

The SAE 30 viscosity ensures reliable lubrication in a wide range of marine conditions, while advanced detergent and dispersant additives control deposits and minimize sludge and varnish buildup in critical engine components. This helps maintain cleaner pistons, improved ring belt conditions, and longer oil drain intervals — all crucial in reducing downtime and maintenance costs in marine operations.

Ideal for use in coastal and deep-sea marine vessels, stationary power units, and auxiliary engines, this oil meets the lubrication needs of high-output, medium-speed diesel engines under demanding service conditions.

Key Benefits:

• 15 TBN for strong protection against acids from sulfur-containing fuels

• SAE 30 viscosity for optimal flow and lubrication in marine diesel systems

• Superior detergency for piston cleanliness and deposit control

• Excellent oxidation resistance for longer oil life and reduced maintenance

• Designed for medium-speed trunk piston marine diesel engines
