Manufacturer's description

Shell Argina S4 40 is a multifunctional crankcase lubricant for highly rated medium-speed diesel engines operating on residual fuel. Shell Argina S4 40 has a BN of 40 and is designed for conditions of high oil stress. In

Applications

• Medium-speed industrial or marine propulsion and auxiliary engines, burning residual fuel oils, which create conditions of high oil stress. These conditions usually occur: In newer engine designs, less than 10 years old and/or fitted with flame rings.
• Where fuels with sulphur >2% are in useShell Argina S4 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.
• In newer engine designs, less than 10 years old and/or fitted with flame rings

Performance & benefits

• Extended oil lifeShell Argina S4 40 is a BN 40 oil which has been optimised to resist oxidation and maintain BN in order to reduce the amount of oil sweetening that is required. 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 S4 40 has a high level of detergency leading to exceptionally clean crankcase, valve deck and pistons. The formulation has been further optimised to reduce deposits in critical areas, e.g. piston undercrown.
• System efficiencyShell Argina S4 40 has a high detergency/low dispersancy formulation in order to effectively release contaminants and water in centrifugal separators. Shell Argina S4 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.
