Performance, Features & Benefits

• Extended oil life

Shell Argina S3 40 is a BN 30 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 protection

Shell Argina S3 40 has an optimised 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 efficiency

Shell Argina S3 40 has a high detergency/low dispersancy formulation in order to effectively release contaminants and           water in centrifugal separators.

Shell Argina S3 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.

Main Applications

Medium-speed industrial or marine propulsion and auxiliary engines, burning residual fuel oils, which create conditions of moderate oil stress. These conditions usually occur:

• In newer engine designs, less than 10 years old
• Where oil consumption is > 1 g/kWh
• Where load factors are <85%
• Where fuels with sulphur <3% are in use

Shell Argina S3 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.
