From a pratical point of view its proberly a bit runny and won't stick to the wings like its meant to.
Also if you are at a controlled airport they have all now moved onto eviromentally friendly fluid. The up shot of this move is that you will go through brakes and shimmy dampeners at 3 times the rate as summer. The stuff eats landing gear.
But as they are using this type of fluid if SEPA do a fluid check in the outflow sump and find horrible de-icing fluild there may be a bit of a witch hunt to find out who has been using it.
