Specs and approvals listed by the manufacturer

  • Meets Mazda FL-22 per Antifreeze is glycol plus inhibitors. Choose it by your vehicle's specification. (Mazda)

Manufacturer wording: MazdaShop: "Mazda Warranty Approved". Mazda owner's manual (2022 CX-9): "If the FL22 mark is shown on or near the cooling system cap, use of FL-22 is recommended when replacing engine coolant."

"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 Mazda FL-22, Mazda lists that code for this product. Read the exact wording above, and confirm against your manual.
  • Sold premixed: pour as supplied. Do not add water unless the label says to.

Note: Pre-diluted at 55% concentration per MazdaShop. Price shown on the store is deliberately not recorded.

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.
