Anything else and your risking mixing something that may break down what your cooling system needs. And there are other variables no one thinks about (except me) like electrolysis (might be misspelled). How is this chemical effect your head gasket? how does it affect the conductivity of the coolant which eats head gaskets? what about lubrication? does it build up in your motor in the hot spots that you cant see?? Trust me.... I have seen plenty of crazy things. the best thing to do is to change it approx every 30,000. Gasoline, oil, coolant, brake fluid, all automotive chemicals have a shelf life just like milk.
