• Improved oxidation & thermal stability reduces deposits build up in crankcase & piston cooling spaces and facilitates better piston cooling efficiency. • Good resistance to the action of water and separation capability improves oil life and provides effective lubrication even in presence of water. • Excellent filtration and centrifuging capabilities. • Excellent resistance to rust & corrosion enhances bearing life. • Excellent TBN reserves provides improved neutralization of strong acids, formed due to burning of high sulfur fuels entering inside the system, which helps in keeping the crankcase & circulation tanks cleaner.
• Suitable for lubricating crankcase systems of low speed cross head marine engines, operating on residual fuels. • Turbochargers, geared transmissions, variable pitch propeller and Oil lubricated stern tubes & bearings. • Deck machinery and other ancillary equipment requiring an SAE 30 or 40 oil specifications.
