I'm still not sure I "get" waterless coolant. It is supposed to be better at cooling than normal coolant, but unless you have an overheating problem, then I don't see much point in changing it - this is more something for older classic cars that don't like sitting in traffic jams. Another downside is that they are oil based and in fact flammable, so if your car still overheats and blows a hose, you will end up with a nice fire as well. So I'm sticking with normal coolant in both my cars.
