Shell Marine has provided evidence of the cost savings available when a customer chooses its medium-speed engine oil Shell[ds_preview] Gadinia, after PT Indo Container Line (ICON Line) confirmed that reduced lubricant consumption led to longer oil-drain intervals and cost reduced by 58 %. Independent laboratory tests confirmed that oil-drain intervals can be extended from 1,500 hours to 3,500 hours, the company stated. Shell Gadinia S3 40 is a multi-functional diesel engine lubricant which is particularly suited for medium-speed main or auxiliary engines burning fuels with sulphur contents up to 1 %, protecting against oxidisation and thermal degradation and minimising lacquering. The engine oil can also help extend engine life by reducing deposit formation in the piston ring belt and cylinder liners, by reducing the risk of ring sticking and breakage.
