Lubricants for medium-speed marine diesel engines running on distillate fuels

Shell Gadinia S3 30 is a high quality, multifunctional diesel engine lubricant which has been specially designed for the most severe service main propulsion and auxiliary marine trunk piston engines burning distillate, hybrid and bio-fuels with a sulphur content up to 1%.
The newly formulated Shell Gadinia S3 30 has also been optimised for use in non-engine applications which are typically found on board such as gearboxes, clutches and stern tubes.

Performance, Features & Benefits

Extended oil life

Shell Gadinia S3 30 offers excellent resistance to oxidation and thermal degradation so it can offer longer oil life, especially in high stress engines under severe operating

Shell Gadinia S3 30 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 conditions.

Engine protection

Shell Gadinia S3 30 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.

Main Applications

Highly rated, medium speed, main propulsion & auxiliary trunk-piston stationary & marine diesel engines.
Shell Gadinia S3 30 will also perform satisfactorily in smaller high-speed engines typically used in fishing fleets which operate under arduous conditions and have small sump.

In addition the new formulation has been designed to minimise laquer formation resulting in greater control of oil consumption and reduced operating costs.

System efficiency

Shell Gadinia S3 30 has been designed to have greater sizes.

Turbochargers, oil filled stern tubes and variable pitch propellers.
Deck machinery & other marine applications requiring SAE 30 viscosity oils.

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 30’s improved water tolerance and separation
in separators.
