Now that my wife has gone and bought a car that uses AbBlue I'm wondering about the cheapest/easiest way of topping up the tank.
I seem to recall reading somewhere that part-used containers shouldn't be stored which sounds like bollocks to me but maybe it does go off when exposed to air? Given that the tank holds about 8L and will probably get topped up before it's empty, that's gonna mean chucking at least 2L of AdBlue at every top-up. Seems wasteful.
What do other folk do?
