System oils
Explore Castrol CDX – our range of system oils formulated for excellent oxidation stability, water handling, engine cleanliness, and protection.
Complete protection for slow-speed engines
The marine industry is evolving rapidly, placing increasing demands on slow-speed engines. While selecting the correct cylinder oil is critical to protect against combustion wear, it is equally important to protect the crankcase. The cylinder and crankcase function together as part of the engine system. If one isn’t operating at peak efficiency, the other can be negatively impacted – affecting overall engine performance and operational reliability.
Operating under extreme pressures, the crankcase requires a system oil that can tackle these conditions head-on.
Castrol’s CDX range of system oils is specifically designed to help provide smooth engine operation, reduce wear, and extend engine life.
Castrol CDX system oils
