i used a mix with dexcool and the royal purple ice stuff when i did my heat exchanger idk if i would recomend running straight waterless stuff need to have some protection properties for cold nights if your in an area that gets cold. dexcool mix also has some lubrication properties to it as well that help y i did a mix of the purple ice with dexcool cant remember exact mix just followed directions on bottle.
i mean i wouldn't run straight chemical personally in my own i would have it mixed with some dexcool. most those chemicals from my taking on them made for like running at the track where just need to get a pass or few down the track not for daily driving. but you may be ok just from a technicians standpoint i wouldn't run it straight.
