I have read the labels for all premix antifreeze that I've seen, and NONE of them have used distilled water in the mix. For that reason, in addition to premix 50/50 being almost double the cost, I always get 100% antifreeze and mix in an equal amount of distilled water myself. I see no reason to ever purchase 50/50 premixed antifreeze, and think it's a bad idea to do so.
