• 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.
