Marine Diesel Trunk Piston Oil 30TBN SAE 30

Our Marine Diesel Trunk Piston Oil 30TBN SAE 30 is specially formulated for trunk piston diesel engines operating on high-sulfur heavy fuel oils in the most demanding marine environments. With a Total Base Number (TBN) of 30, this oil offers unparalleled acid-neutralizing capability to combat corrosion caused by fuel sulfur content, ensuring long-term engine reliability.

The SAE 30 viscosity grade delivers stable lubrication and a strong oil film under continuous high-load and high-temperature operation. Its advanced additive system provides superior detergency and dispersancy, keeping pistons, liners, and ring grooves clean while minimizing sludge and varnish formation.

Manufactured from high-quality base oils and optimized for extreme marine service, this oil ensures outstanding oxidation stability, extended drain intervals, and reduced maintenance costs.

Key Benefits:

• Extremely high 30 TBN for excellent protection with very high-sulfur fuels

• Outstanding corrosion and wear protection under severe operating conditions

• Superior detergency for cleaner pistons and reduced deposit formation

• Excellent thermal and oxidation stability for long oil life

• Designed for trunk piston engines in deep-sea and heavy marine operations

Ideal for operators requiring a SAE 30 marine system oil with 30 TBN to protect engines burning residual fuels in harsh marine environments.
