SEAOIL MARINE 412 is a premium trunk piston diesel engine oil (TPEO) formulated using high-quality base oils and advanced marine additive technology designed to provide reliable protection for medium-speed diesel engines operating on distillate fuels.

The formulation provides excellent detergency, dispersancy, oxidation stability, and alkalinity retention while maintaining effective water separation characteristics and engine cleanliness during operation. It is engineered to minimize wear, reduce deposit formation, and support reliable engine performance under severe marine and stationary power generation operating conditions.

SEAOIL MARINE 412 is suitable for medium-speed trunk piston diesel engines in marine propulsion and power generation applications requiring SAE 40 viscosity grade lubricants with TBN 12 performance characteristics.
