When the SR71 blackbird was first developed the local water was used to cool the titanimum forgings and they were cracking. Later it was found that the Fluorine in the water to prevent tooth decay was weakening the metallic structure. Crud matters especially when it circulates for a long time.
I would have kept the green stuff in my car if it were not for the deposits that I found in it. This was in response to codes that the engine was throwing a while back.
Woody, use what you like and feel good with but always consider Distilled water, Wal-Mart for about 58 cents /Gallon. Enjoy
