I was attracted to the long life part of it. I have owned my Bonneville for 35 years and plan to keep it until I die. If it truly lasts forever and minimizes pump, hose etc. deterioration, then it brings the actual price down quite a bit.
It is not really much of a stretch to think they could improve engine coolant over the past 40, 50, or 60 years, like they have oil. I know the issue with zinc and flat tappet cams, but todays oil, compared to the non detergent oil or even detergent oil from the 60s lubricates and cleans much better. Why not coolant too?
