Be glad that the motorcraft antifreeze play well together. I have a 13 Chrysler and the Chryslers had massive problems with heater cores plugging and non mixable antifreeze. The earlier days of dexcool had sludge/jelly problems when mixed wrong. I dumped the OEM Chrysler antifreeze and went with the autozone extended life in my Chrysler a long time ago. It's compatible with all types so I don't have to worry about someone topping it off with the wrong stuff.
Hopefully the industry will settle down and agree on something soon. It's nuts. A quick google search will get you out in some forum of nerds arguing about OAT, POAT, NOAT, and IAT antifreeze. Then there is truck antifreeze. All we sell at work is TRP extended life and it is rated at 1,000,000 miles 8ys. It is OAT.
TRP is the quality choice for aftermarket truck parts. Available for almost all makes and models, you can find TRP in over 300 locations across the country.
