In the entire realm of vehicle maintenance, the selection of a PROPER coolant is certainly one of the most convoluted, excruciating adventures an owner will ever experience. With the exception of some technically knowledgeable folks on this and other similar forums, it often appears that general public information about coolants and engine compatibilities may be painfully absent. The price ($$$) that a vehicle owner could pay for an incorrect coolant selection could be steep.
The problem is compounded by 'opinions' offered in lieu of facts and a certain obfuscation or glossing of details by coolant manufacturers on their labels. For example, what is the informative value of a coolant manufacturers generic statement that the coolant 'meets XXXXX car brand requirements' when that car manufacturer offers several models with different engine sources factory filled with differing coolants, some of which should NEVER be mixed or replaced with something dissimilar.
I guess the only solution to the issue is to adhere to manual specs, keep informed through research, be skeptical of generic label claims, and value 'opinions' as food for thought, to be confirmed upon further examination.
