FAQ
What do ACEA E9 and API CK-4 mean
They are heavy duty diesel oil categories. E9 and CK-4 use low SAPS chemistry that supports engines with after treatment when specified by the maker.
Is 15W-40 E9 CK-4 suitable for DPF systems
Yes, when the handbook calls for E9 or CK-4.
Can I mix with other grades
Top up with the same grade and level where possible. Return to the specified oil at the next service.
