The Prestone "any color" is basically the G05 type coolant used by Ford and Chrysler when they didn't jump on the Dex bandwagon. I'm with Buttermore on this, and have switched to the "any color" some time ago...before my forum days, too!
I tored down an abused Ford 3.8 to replace the gaskets, and the pitting and other problems were not anywhere near what I've seen with the Dex on well cared for engines. I don't know for sure if the Prestone is Dex, or Dex compatible...or if it is just compatible, does the compatibility give it the same acidic qualities? I'm not sure, but it'* not worth it to me to find out.
BTW - if you go to Valvoline for a top off, or flush and fill, you'll get the "all color" G05. That'* likely both a business decision of not needing to stock both, but also as they are the major distrubutor of the G05 coolant.
I would not recommend the compatible stuff for any car that did not have have Dex to begin with. I had flushed out the green stuff in 3 cars that didn't have it originally (2 GMs 1 Chrysler) and then used the Prestone Long Life Dex Compatible. Within a year, all 3 needed water pumps. Coincidence, and would have needed them anyway? I don't know, but the odds would seem against it. Again, it wasn't worth it to me to find out, so they got the "any color" stuff.
I did a search a while ago, one of the other times that we discussed this, and found this article which had a good explanation regarding the two.
