I have only ever used Century Heat Transfer fluid. There seems to be a lot of leeway in the guidance people have been told. I read that Newmar recommends changing when pH goes below 8.0. ITR has evidently said, 10yrs, pH below 7.0, and hardware is stainless...don't worry.ITR told me that color doesn't mean it's old. Color will change with different types of hydronic fluid added.
I'll see how I feel about it in another 10 years. By then I may know people who have kept the same fluid for 20 years without issue.
It was nice to have had the experience. Should I ever need to purge air from the system...I now have the rig and experience.
