Using Engine Ice
I first put it in my 1980 Goldwing instead of the Honda Coolant and noticed a pretty good drop in temp. I live at the top of a long hill, and in summer, everything I drive is warm as I pull in. The Goldwing no longer got warm enough to kick in the aux fan. Subsequently, I put it in the Concours I had. Now I have it in my Voyager. I cannot say that either the Concours or the Voyager run "cooler", except that it takes longer and higher ambient temps for the aux fans to kick in.
From what I gathered in my research before I ever installed it, it is a good quality coolant with excellent corrosion inhibitors and mechanical seal (water pump) lubrication qualities. I have used it for six years now with no problems on anything I have used it in (including the original Goldwing I used it in, which I still own). I also installed it in my Daughter's Honda scooter that she rides all over Seattle. It's nice to just have one coolant that I use in all the bikes/scooters.
