It can be used in both turbocharged and naturally aspirated engines running either low or high sulphur diesel fuel. It is especially suited to coastal and fishing fleets but can also be used in recreational craft.
Marine Diesel 15W-40 is formulated with additive technology that is highlighted by the inclusion of special corrosion inhibitors as well as a high TBN (Total Base Number) content, allowing it to be able to achieve long oil drain requirements while providing outstanding engine protection for the life of the oil drain. It will provide excellent protection of engine components and resistance to oil thickening due to soot build up as well as start-up wear protection of the engine valve train.
Marine Diesel 15W-40 can be used in marine engines manufactured by Caterpillar (except for 3600 series), Cummins, Iveco (except C13 ENT M77), MAN, Mercedes Benz, MTU, Perkins, Scania, Volvo and many others.
