Castrol VECTON 5W-40 CK-4/SN Diesel Engine Oil
Advanced Synthetic SAE 5W-40 Heavy-Duty Diesel Engine Oil
Castrol VECTON 5W-40 CK-4/SN is an advanced synthetic heavy-duty diesel engine oil formulated for high-speed 4-stroke diesel engines that require an SAE 5W-40 lubricant meeting API CK-4 or API SN performance requirements.
It is suitable for diesel engines operating with a broad range of fuel qualities and is compatible with engines equipped with exhaust gas recirculation, or EGR, systems. Castrol also states that the oil is API service backward compatible where an SAE 5W-40 viscosity grade is required.
Castrol VECTON 5W-40 is engineered to support longer useful oil life in demanding heavy-duty diesel applications while meeting specifications from major engine and equipment manufacturers.

API CK-4 and Backward Compatibility
API CK-4 is a heavy-duty diesel engine oil category used in many modern diesel applications. Castrol states that VECTON 5W-40 CK-4/SN is API service backward compatible where an SAE 5W-40 viscosity grade is required.
Backward compatibility does not eliminate the need to verify the engine manufacturer's viscosity and specification requirements. Always confirm that SAE 5W-40 and the applicable API or OEM specification are appropriate for the engine.
EGR Compatibility
Castrol VECTON 5W-40 CK-4/SN is compatible with diesel engines fitted with exhaust gas recirculation systems. EGR systems recirculate a portion of exhaust gas through the engine, making proper lubricant selection important for engines designed around this emissions-control technology.
