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; and main & auxiliary trunk piston engines burning on low sulfur distillate 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
