"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.
Compatibility notes
- If your owner's manual calls for VW TL 774-G, Zerex lists that code for this product. Read the exact wording above, and confirm against your manual.
- Colour is listed as Pink. Colour is a dye, not a spec, so two coolants of the same colour can be different chemistries. See coolant colours explained.
- Sold as a concentrate: dilute with distilled or deionised water as the label directs. See premix vs concentrate and the freeze and boil calculator.
Note: Valvoline PI sheet hosted by a distributor. Valvoline calls it a "hybrid carboxylate formulation" with organic acid technology; it does not use an acronym on the sheet, so chemistry is left "not published".
