Walmart AF is as noted a Dexclone, ie, an OAT AF containing 2eha found in DexCool. As for the newer Prestone AF, even though it's been noted to now contain phosphate which is also found in Asian PHoat AF, it still contains 2eha found in Dex. So because of that, I'll call it a modified Dexclone.
Also I have lost some trust in the Prestone brand since they introduced two Prestone AF premix in half gallon jugs, one labeled for Toyota, one for Honda. Both use 2eha as inhibitor which no Asian vehicle AF contains, uses or recommends. I would not use it, or advise anyone to use it in an Asian vehicle. Not to mention there are true (no 2eha) Asian PHoat premixes like WM Valvoline Asian Vehicle, ZAF readily available for the same or less money.
To the topic, Ford still specs Conventional/Original Green for the topic vehicle. For whatever reason(s) they didn't back spec any of their current AFs including the Dex Orange they now use. So, I'd just continue to use a Conventional Green. It can still be found in a concentrate for a reasonable price
