It's not my responsibilty to prove Global doesn't need the inorganics either. You haven't proven that it does.
The fact that Asians want phosphates proves the replacement coolant should contain the same.

No. Peak created Global in order to get rich. It's called a patent. This is why GM licenses the use of the formula and the word of their [censored] product to other companies for use. It's all about money.
It' s not just about money, but meeting a standard and compatibility and reputation. Peak claims compatibility. G-05 doesn't, and do you think G-05 production isn't about money too?

No. You simply don't possess the knowledge. Back in the 1990s, there was a push here in the US for longer life coolant. GM was the first with Deathcool. Ford and Chrysler checked into it and Chrysler decided not to use it and Ford used it from 1999-2002 in the Mercury Cougar and the EV Ranger. Ford and Chrysler both went to G-05 around 2002 which had been used in Europe for numerous years.
I don't possess this knowledge? If you say so. What was Dexcool replacing? Green. If you are trying to say G-05 was back-speced for Green by a manufacture, that is not the real reason why it was selected in the first place. You acknowleded that G-05 was a European long-life coolant for some time, so it was chosen by Ford and Chrysler to replace Green, just as Dexcool was first chosen by GM. You are kind of going in circles here I think, and I'm not really getting your point. Anyway, Your reply here really had no relation to the reason I disagree with you in the other thread.

Using the Zerex Application Chart, the GM specs for green coolant are GM1825M and GM 1899M. Both of these are met by G-05 yet are not met by Deathcool. Therefore, these specs cannot be met by Deathclones such as Super Tech, Peak, and Prestone.
So since Ford and Chrysler went from green to G-05, it can easily be assumed that G-05 is the direct replacement to green.
First off I think I think Zerex's Application Chart is a bunch of baloney. I think they recommend Dexcool for just about everything on one of their charts I've seen. To use your statement earlier, it's all about $$$. Of course Dexcool is not going to meet GM spec for Green. Now, I think I see what you are meaning by "G-05 is a direct replacement for Green". G-05 is very similar to Green and because of the OAT it has a longer service life than Green. But keep in mind we are not talking about filling classic cars that maybe ahve iron blocks, brass radiators etc, that originally were factory filled with Green. Those cars should get Green anyway, and perhaps you're right G-05 is the next most compatible choice. We were discussing cars that did not come with green originally. Also what you are saying only supports my staements earlier that Green worked fine in Asian cars.

THERE IS NO PREFERABLE ORGANIC SUBSTITUTE FOR PHOSPHATES OR SILICATES! And this is why HOAT coolants such as G-05 and Asian are used by automakers requiring phosphates or silicates in their coolants.
That is a bold statement that isn't support with real facts. Dexcool might very well protect against corrosion as well or better than those two with out these inorganic inhibitors. And also Peak Global might too. Silicates and phosphates are not th same thing anyway. Dexcool, protects very well against corrosion of aluminum if no air is present in the cooling system. How many times do I have to say that?
