I applaud your persistence and knowledgeable you looked that up, everyone should but I never said absolutely do not use anything for sure or created some old wives tale out of lack of knowledge, on the contrary I DID do much homework. For every piece of literature out there, there is still confusing material to counteract and conflict it and I still trust NO ONE other than the proverbial owners manual and manufacturers recommendations direct from Chrysler!!
Look up GM's problem 10 to 20 years ago mixing coolants caused heater cores and engines to gum up and fail when other written literature said it was okay, was a class action lawsuit.
(Use others at your own risk/Don't take a chance/why take a chance/ Use only what Chrysler tells you by their manufacturer)
I am still not changed one bit and would never add anything else including different colors on top of the Chrysler brand... Are you going to run into catastrophic failures if you use peak for 10 years in the new Pacifica that's prone to head gasket failures?? who knows probably not but again my whole point is why take a chance for $7 more a gallon.. Should Chrysler's beautiful purple with its magic ingredients and specific properties be mixed with Auto Zone universal orange or green?? probably won't hurt anything but why take a chance....Yes don't mix OAT and HOAT at least for starters and most ethylene glycols should mix to some degree..
