Lubricants for medium-speed trunk piston engines
Shell Argina S3 40 is a multifunctional crankcase lubricant for highly rated medium-speed diesel engines operating on residual, blended or distillate fuels. Shell Argina S3 40 has a BN of 30 and is designed for conditions of moderate oil stress.
Shell Gadinia S3 40 offers excellent resistance to oxidation and thermal degradation so it can offer longer oil life, especially in high stress engines under severe operating conditions.
Shell Gadinia S3 40 can help to extend engine life by reducing deposit formation in the piston ring belt and cylinder liners reducing the risk of ring sticking and breakage.
In addition the new formulation has been designed to minimise laquer formation resulting in greater control of oil consumption and reduced operating costs.
Shell Gadinia S3 40 has been designed to have greater tolerance to engine overload or poor combustion. It will also offer a greater safety margin to protect highly loaded bearings, in the event of water contamination, due to Shell Gadinia S3 40’s improved water tolerance and separation in separators.
Shell Gadinia S3 40 is also approved for use in a number of non-engine applications such as gearboxes, clutches and stern tubes – this can help smaller operators to minimise inventory by removing the requirement to keep multiple specialist lubricants on board.
