Castrol begins global rollout of new Cat II cylinder oil

Castrol Cyltech 40 XDC is suitable for LNG and methanol-fuelled ships, as well as ships using conventional marine fuels. The cylinder oil can help ship operators transition to alternative fuels – with no compromise on performance.

Castrol Cyltech 40 XDC achieved Category II Status from MAN ES in July 2022, having attained a Category II No Objection Letter (NOL) after extensive field testing. MAN ES introduced the new performance category for Mark 9 and above two-stroke engines after these engines were recognised to require cylinder oils with excellent overall performance and a special focus on cleanliness. The new cylinder oil performed equal to or better than a classical 100BN category II reference oil. 

Castrol Cyltech 40 XDC is suitable for all MAN ES engine types and is recommended for MAN B&W two-stroke engines Mark 9 and above. There is also no need to alternate between high-BN and low-BN cylinder oils for cleaning-up purposes when it is used, and no need for additional tankage, with one oil for all operations requiring 40BN cylinder oil. This, along with ship operators being able to use one lubricant across their entire MAN fleet, can help simplify marine operations as the external environment becomes more complicated. 

Expansion Plans

The new cylinder oil will be rolled out across Hong Kong followed by the Chinese ports of Beilun, Dalian, Fangchang, Qingdao, Rizhao, Shanghai, Taiceng and Yantai. 

This expansion is then intended to continue in the next few months into Europe and the USA, including Belgium, the Netherlands, Spain, Gibraltar, the Canary Islands, Los Angles, Houston, New York and New Orleans.  

Finally, the cylinder oil is intended to be launched in Singapore and Panama. At this point, based on ongoing analysis of demand worldwide, Castrol will also decide whether to expand availability further, particularly in the rest of the USA and Europe.
