Use Prestone Long Life, the one in the silver jug.  It is Phosphate free, it says so on the label.  Also, any Dex-Cool compatible anti freeze is also phosphate free.  Concentrated or pre-mix, concentrated is better to carry with you as you have more in the same space.  The water you mix it with is not that important u less you have some bad water on hand.  I’m on a well here and been using that well water for 25 years, my van and all my customers vans.
