Manufacturer wording: OEM Approvals:

"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, Comma lists that code for this product. Read the exact wording above, and confirm against your manual.
  • Chemistry is listed as Si-OAT. Mixing different chemistries can shorten coolant life. See OAT vs HOAT vs IAT and use the mixing checker before topping up.
  • Sold premixed: pour as supplied. Do not add water unless the label says to.
Always check your owner's manual first. Use the coolant spec printed in your owner's manual or service information. A listing here is the manufacturer's own claim (meets, exceeds, approved or recommended, worded as they put it). It is not our approval and not a fitment guarantee for your vehicle. If in doubt, ask your dealer or a qualified mechanic.
