How can a conventional green coolant be long life? What's in it that makes it long life? Surely it has to have some kind of OAT in it?
Good questions, and there was a recent discussion on Zerex Green and how it could claim 5 year service interval. I will swear that on Amazon, a claim of using an OAT inhibitor was made. After an inquiry to Zerex, the Amazon Zerex Green entry with reference vanished. Zerex basically said they do not use an OAT inhibitor in Zerex Green. If it did then it would not truly be an IAT AF, original/conventional green. It is a low silicate formula, which would help with a lengthened service interval. Beyond that it seems a question mark.
That said, if the price was right for the concentrate, I'd have no qualms about using it for conventional green applications.
Edit. Looks like link to referenced discussion posted before I finished my post. Be that as it may, post here summarizes what was said from my perspective.
