Marine Lubricants

Medium-speed truck-piston diesel engine oil

Ocean 40/30 Ultra is a multifunctional crankcase lubricant for certain medium speed diesel engines operating on residual, blended or  distillate fuels.
Ocean 40/30 Ultra is used in medium and high speed engines burning distillate fuel, where a high TBN, high ash lubricant is suitable. These oils are used in Marine engine reduction gears and certain other ship-board applications, where specialist lubricants are not required.
