I think kschachn has the right answer.
I've used Mopar and Zerex G05 in my 08 Jeep, as recommended by Jeep, changing it ever 5 years. It is now 13 years old and has 138k miles on it and the cooling system appears to be clean and healthy. I doubt anything's been destroyed in it. Even the original water pump appears to be going strong, with no unusual play, noise, or even seepage.
I think putting a coolant formula not specified by the manufacturer could potentially cause some problems, though.
