Castrol’s new Vecton 15W-40 CK-4/E9 with ‘System Pro Technology’ is a new diesel engine oil standard introduced by API.
API CK-4 has three improvements over CJ-4 lubricants: oxidation performance, aeration performance and shear stability.
This translates into a higher performing lubricant capable of withstanding higher temperatures and pressures experienced in modern engines.
CK-4 is backward compatible to previous categories API CJ-4, CI-4 Plus and CI-4. Volvo 4.5 has even stricter test limits than API CK-4 and offers improved oxidation performance.
