Cost: Type IV versus Type II
Folks,
Anyone got any idea of the relative costs of these de-icing fluids per litre? I seem to recall from a few years back that Type IV was almost double the cost of Type II.
My reason for asking is that on a real crap morning like I had a couple of days ago, with freezing fog, then I'll always take the best option; Type IV no matter what. But on a gin clear, cold morning with just some frost on the top and no hint of further precipitation, then Type IV might be overkill, and a two-step hot type II just as much use, and more cost effective. Wouldn't mind being able to tag some figures on to this conception.
Appreciate any heads up. Thanks.
