Crosshead Engine – Cylinder Oils
CASTROL CYLTECH 70 (SAE 50) BN 70
Castrol Cyltech 70 supersedes and replaces Castrol S/DZ 70. Developed to provide superior performance at the higher temperatures and pressures in modern engines, it is suitable for the lubrication of the latest super long-stroke crosshead engines, and indeed for all slow-speed marine diesel engines burning residual fuels.
CASTROL CYLTECH 50 S (SAE 50) BN 50
Castrol Cyltech 50 S is a premium marine diesel engine cylinder lubricant for two-stroke crosshead engines running on low sulphur fuels. Its Base Number (BN) is carefully levelled (at 50 BN) to meet certain customers’ requests for improved flexibility when ships switch from low to moderate sulphur fuels. Cyltech 50 S covers a wider range of fuel sulphur levels than a 40 BN oil.
CASTROL CYLTECH 40 SX (SAE 50) BN 40
Castrol Cyltech 40 SX is a highly detergent, premium marine diesel engine cylinder lubricant for two-stroke crosshead engines running on low sulphur fuels. It is a 40 BN cylinder lubricant for the applications of prolonged operation on low sulphur fuel (distillate or heavy fuel <1.5% S).
