i previously would run distilled water with water wetter, but i just flushed out the system and put in straight engine ice for the simple fact that its good to -27 as you mentioned. you do not mix the engine ice with water, its premixed. its also legal with most racing and trackday organizations which is an added benefit. id just get some fresh engine ice and be done with it. btw, if you use antifreeze and distilled water, you can buy distilled water at almost any supermarket or pharmacy.
