JCL is correct -- it isn't miles, it is how those miles are accumulated (and the climate has to be considered too).
On the ones that have failed, anyone using anything but BMW coolant (plus water, of course)?

Right, I understand that the mileage is not the only factor but I wanted to to get some feedback. I haven't seen anybody with NPG+ yet on X5 although there are quite a few guys on e39/38 forums that use it successfully. I assume that will put much less stress on the radiator and the whole cooling system. NPG+ is a high boiling temp cooling fluid.
