Excellent oxidation & thermal stability reduces deposits formation in piston under crown and ring belt areas.
Outstanding protection against ring and liner wear.
Excellent protection from rust and corrosion even in presence of water.
Excellent oil filtration and centrifuging capabilities.
High detergency & low dispersancy capabilities, ensures engine cleanliness and releases contaminants & water readily in centrifugal separators.
Very high TBN reserves & retention, gives rapid neutralization of strong acidic combustion products and provides long term protection against corrosive wear of ferrous & non-ferrous metals.
Suitable for lubricating Medium-speed Trunk piston engines in industrial or marine propulsion and auxiliary engines on deep sea vessels, burning on residual fuel oils with sulfur levels of 1.5% to 3.5%.
Suitable for use in the latest model medium speed diesel engines, facilitating low crankcase oil consumption and useful in engines operating with low cylinder liner temperatures.
Marine engine reduction gears, stern tubes & bearings and certain other ship-board applications.
