SEAOIL Marine Oil 4012 (TBN 12, SAE 40)
SEAOIL Marine PROMAR 4012 is a trunk piston diesel engine oil (TPEO) developed for use in medium speed diesel engines in marine vessels and power generation applications. SEAOIL Marine PROMAR 4012 is formulated with high-performance base oil and additive system that provides superior water shedding characteristics combined with detergency, dispersancy and alkalinity properties necessary to minimize wear and maintain engine cleanliness.
Performance Standards
Applications
- Medium-speed trunk piston engines burning distillate fuels in marine main and auxiliary power plant service
- Medium-speed trunk piston engines burning distillate fuels in stationary power plant service
- Can also be used in engines that use distillate fuels of lower viscosity (80-100 Cst @ 50 C) and lower sulfur content (up to 1.2%mass)
Benefits
- Maintains power output
- Its detergent and dispersant additive system provides control of high temperature deposits in areas such as the undercrown of the piston and the piston ring belt area, enabling piston rings to function efficiently.
- Prolongs oil life
- Its Base Number (BN) level and superior alkalinity retention characteristics maintain adequate BN to ensure effective neutralization of corrosive acids formed by the combustion of fuel with sulfur, thereby minimizing liner wear
- Efficient system performance
- Its excellent water separation characteristics enable water to be centrifuged out with essentially no loss of additives
