Prestone Extended Life antifreeze is labeled to be phosphate free.  Peak antifreeze is not so labeled, nor is Prestone "regular."

May be that only a handful of companies make antifreeze.  If so, they are putting out a bunch of different labels with different colors of dye, like blue, red, yellow, green ............... .  Purple and orange for all I know.  A few years back, antifreeze was green, period.  Then car companies started with their own labels and colors, and admonitions to use only "approved" coolant, which they helpfully (for themselves) chose not to define.  Now ??????????  Most antifreeze, as has been stated on the list repeatedly, states on the label that it is compatible with all other brands and colors, and is suitable for all engines.  But, that's from the maker/seller.  How are we to know?  But if the label specifies "phosphate free," I'll accept that.  For now, because when I was getting cooling system work done I couldn't find any labeled as phosphate free, my waterboxer has VW brand blue stuff.  Next time, I'll get Zerex or Prestone long life stuff that is labeled as phosphate free.

I've mostly lived in places that had very hard water, except for a stint in Kentucky.  At least with hard water, the lead in the copper-line solder in the house pipes stays put, rather than mobilizing.
