Manufacturer wording: EXTRA Mixed-Fleet Global Extended Life – recommended for use in all makes and models of passenger vehicles, light duty, and heavy-duty diesel vehicles (on-road, off road, construction, farm applications)
"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
Designed for use in all makes and models of passenger vehicles, light duty and heavy-duty diesel vehicles including on-road, off road, construction, and farm applications.
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.
