Specs and approvals listed by the manufacturer

No OEM approval or spec codes are published on the source we checked. That does not mean the product fails any spec. It means the manufacturer did not list one there. Check the product label or ask the manufacturer.

Compatibility notes

  • Chemistry is listed as 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.

Note: Fleetguard data sheet hosted by a distributor. Heavy-duty diesel/gas/natural-gas engines.
