Petromin PETROPOWER-4 / PETROMAR-4

DESCRIPTION
Petromin Petropower-4 Oil Series is highly alkaline Trunk Piston Engine Oil for crankcase and cylinder lubrication requirement of medium-speed high BMEP marine engines burning high sulphur residual fuels (3.0% - 5.0% sulphur). They are developed for ‘flame ring liners’ operating on high sulphur residual fuel in these engines. Petropower-4 shall take care of TBN depletion problems since in some engines it will be severe due to low oil consumption.

APPLICATIONS

Petromin Petropower-4 Oil Series is recommended as crankcase engine oil for medium speed high BMEP engines, operating on high sulfur fuels. Particularly suited for ‘flame ring liners’ fitted engines such as WARTSILA, MAN (B&W) latest models designed for low oil consumption. Petropower-4 oil can also be used as ‘top up’ oil to increase TBN level in medium speed trunk piston engines.


BENEFITS

• Excellent TBN retention with low oil consumption.

• Cleaner pistons, ports and cylinders, thus extending overhauls.

• Fast separation from water in case of water contamination.

• Extended oil life and drain intervals.

• Low under crown deposits.

• Controls sludge formation, thus increase filter life and reduces cleaning frequencies.
