Our range of marine cylinder lubricants, Castrol Cyltech, prevents deposits and corrosion in your slow-speed engines.
Engines face lubrication challenges due to varying fuel sulphur levels, feed rate optimization requirements and operational conditions. Our range of two-stroke marine engine lubricants, Castrol Cyltech, provides optimal protection against corrosive and mechanical cylinder wear. We’ve formulated every product in this range with special care to ensure you get the right balance of base number (BN) and detergency to protect your engines.
* MAN Energy Solutions (MAN ES) no objection letter for category II cylinder oil Cyltech 40 XDC, 40BN, SAE 50 from Castrol.
** Tests were performed as per the MAN ES category II approval process and Castrol Cyltech 40 XDC was recommended for use with MAN B&W two-stroke engines Mark 9 and higher. Different engine types and different engine operation conditions may require different cylinder lubrication feed rates and or oil type.
*** Based on no harms vessel trials carried out by bp on B30 and B50 biofuel blends with residual fuel (VLSFO) lubricated by Castrol Cyltech 40SX.
No two vessels are the same, which means you can’t afford to make assumptions about BN levels across all cylinder lubricants. Castrol Technical Services can help ensure you are using the appropriate lubricant, along with the right feed rate, and monitoring approach to maximize long-term performance. We’ve got an unbeatable depth of engineering knowledge and skills to work with you on a one-to-one basis. Our SmartGains methodology is designed to maximize the operation and productivity of your asset, prevent unnecessary costs and delays, and optimize the ordering process. And with LabCheck it’s easy for you to get the right data at the right time, identify every potential saving, and minimize unplanned downtime.
