Manufacturer's description

Lubricants for medium-speed trunk piston engines. Shell Argina S2 40 is a multifunctional crankcase lubricant for highly rated medium-speed diesel engines operating on residual, blended or distillate fuels. Shell Argina S2 40 has a BN of 20 and is designed for conditions of low oil stress.

Applications

• Medium-speed industrial or marine propulsion and auxiliary engines, burning residual, blended or distillate fuel oils, which create conditions of low oil stress. These conditions usually occur:
• Where fuels with sulphur <2% are in useShell Argina S2 40 can also be used in marine engine reduction gears and certain other ship-board applications, where specialist lubricants are not required. Advice on applications not covered in this leaflet may be obtained from your Shell Representative.

Performance & benefits

• Extended oil lifeShell Argina S2 40 is a BN 20 oil which can be used with multiple fuel types. Please contact your Shell technical representative who will be able to offer additional support in product selection and guidance on extending oil life and minimising sweetening.
• Engine protectionShell Argina S2 40 has an optimised level of detergency leading to exceptionally clean crankcase, valve deck and pistons.
• System efficiencyShell Argina S2 40 has a high detergency/low dispersancy formulation in order to effectively release contaminants and water in centrifugal separators. Shell Argina S2 40 can be used to top up engines already running on any other member of the Argina family, giving immediate control of BN without the need for an oil change. Shell Argina S2 40 may be particularly applicable as a balancing grade for engines which switch between residual fuel and distillate operation.
