Optima Marine 153 is a top quality marine diesel crankcase lubricant blended from highly refined base oils and a specially developed additive package to produce a moderately alkaline product having a Total Base Number of 15 and exceptionally high film strength.
Optima Marine 153 is particularly effective at preventing the formation of black sludge. Optima Marine 153 is recommended for the lubrication of medium and high speed trunk type marine diesel engines operating on fuels containing sulphur levels up to 1%.
Optima Marine 153 provides excellent engine cleanliness particularly in the piston ring area. Its alkaline characteristics prevent engine corrosion by neutralising acidic combustion products thereby providing long service life. While ideally suited to trunk piston engines with low oil consumption of modern design, Optima Marine 153 can also be used in older engines.
