Waterless Coolant

Anyone using waterless coolant?
My full service is coming up and i'm considering a coolant flush and putting this in. Is there a good or bad side to this? Mines a 1.9 M43 engine.

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.

Good enough reason not to change then. I blame wheeler dealers!
