Specs and approvals listed by the manufacturer

  • Meets JIS K2234 per Antifreeze is glycol plus inhibitors. Choose it by your vehicle's specification. (Japan (JIS))
  • Meets ASTM D3306 per Recochem (industry test standard)

Manufacturer wording: OEM Extended Life BLUE I Antifreeze/Coolant meets or exceeds performance requirements ASTM D3306 and JIS K2234.

"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.

What the manufacturer says it is for

It is fully compatible with other similarly formulated extended life coolants and is recommended for use in Acura, Honda, Subaru and newer model foreign cars and light duty vehicles.

Quoted from the manufacturer's page. Coolant.com has not verified fitment for any vehicle, and a listed make or year range is the manufacturer's statement, not ours.

Compatibility notes

  • If your owner's manual calls for JIS K2234, Recochem lists that code for this product. Read the exact wording above, and confirm against your manual.
  • Colour is listed as Blue. Colour is a dye, not a spec, so two coolants of the same colour can be different chemistries. See coolant colours explained.
  • 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.
