This post is seven years old! One of the coolants is Premium Gold G-05 the other is Dexcool. How old is the vehicle?

This will tell you what Ford recommends:

I would be too chicken to try Dexcool in an older Ford.

Its right in the Data sheets you provided "Use only when specified. Do not use this product in systems originally equipped with any green-colored, conventional engine coolant such as Motorcraft® Premium Engine Coolant, meeting Ford Specification ESE-M97B44-A, or with the yellow-colored, longer-life Motorcraft® Premium Gold Engine Coolant, meeting Ford Specification WSS-M97B51-A1, or with the dark green-colored Motorcraft® Specialty Green Engine Coolant, meeting Ford Specification WSS-M97B55-A"............. So if yor vehicle came with Premium gold stick with it.

I have recently been examining BASF's reference material on European market coolants. BASF makes a good portion of the European OEM and did the fundamental engineering on two common American coolants made here under license: DexCool and G-05.

Here's a recap of BASF's families of coolants followed by URL's for some of them. Notice there are three DexCool type coolants, G 30, G 33, and G 34, but no Japanese-equivalents of the Honda and Toyota coolants:

For what it's worth, I still miss your posts.
