Absolutely NOT true. (Edit) - while HOAT may be a hybrid of OAT and IAT
TECHNOLOGIES, it is by no means a "mix" or "combination" of the two. Wording is the key. Just because the two technologies were hybridized into HOAT does NOT mean the two can be mixed together.
Very well said!
Here you go.

What do IAT and OAT mean?
As we have seen, Inorganic acid technology (IAT) is the chemical composition for the traditional green, yellow or blue antifreeze.
Organic acid technology (OAT) on the other hand is a Long Life Coolant usually made of ethylene glycol and is commonly used in Europe. It also has a vastly superior recommended replacement is 5 years or 240,000km
Hybrid Organic Acid Technology (HOAT) is a combination of IAT and OAT with nitrites and actually existed prior to the development of OAT technology. The generally recommended replacement interval is 3 years or 240,000km

AGAIN I STATE I DID THIS WITH MOPAR COOLANT HOAT/OAT AND IT WAS JUST FINE.
