Wow.  I didn't know this.  Distilled huh.  Looks like I'll be flushing mine again soon.  I suspect that its not even phosphate free.  
Why is it that Phosphate free is required, anyway?

Thanks and thanks for the thread.

       Every 2 Years is Probably the Best Rule Of Thumb on This ~ But there are some Variables that can come into play here ~

If You use a Known High Quality Coolant + Distilled H2O You can Probably Get Away With Stretching that A Bit ~ Especially If Your

       If Your H2OBoxr is in a Van that is Only Driven During the Warm Months, A 2Yr Max ROT Should Probably Be Adhered To ~
