For those of us below the freeze line in the country. Most motorcycles just run distilled water and water wetter for coolant at the track. I'll probably just top off whatever is lost with distilled water. For future drain/refill would it be acceptable just to fill up with distilled water/water wetter? A test I saw showed a coolant mixture providing the highest coolant temps, all distilled water dropped it about 10f degrees and distilled water+water wetter dropped 15-20f degrees in the coolant temps. Obviously, living above the freeze poses a problem for those cars but I was curious what your thoughts were on this. Idk if longevity would pose a concern with that route versus the 75k interval the ford coolant provides.
