Manufacturer's description
Lubricants for medium-speed trunk piston engines. Shell Argina S3 30 is a multifunctional crankcase lubricant for highly rated medium-speed diesel engines operating on residual fuel and bio-fuels. Shell Argina S3 30 has a BN of 30 and is designed for conditions of moderate oil stress.
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:
- Where fuels with sulphur <3% are in useShell Argina S3 30 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 S3 30 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 protectionShell Argina S3 30 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 efficiencyShell Argina S3 30 has a high detergency/low dispersancy formulation in order to effectively release contaminants and water in centrifugal separators. Shell Argina S3 30 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.
