Shell Gadinia S3 40 is a high quality, multifunctional diesel engine lubricant which has been specially designed for the most severe service in main propulsion auxiliary marine trunk piston engines burning up to 1% sulphur distillate and bio-fuels. 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.
