"Meets X per manufacturer" is our shorthand for any of the manufacturer's own phrases: meets, meets or exceeds, approved, or recommended for applications requiring. It is the manufacturer's claim, not an approval by Coolant.com or by the vehicle maker. Codes are copied as published. Some sources list codes for compatibility rather than formal approval. The wording above shows which.
