I know your trying to save money but why not go with what is recommended your only spending about 15 dollars more on service you wont need to do for 60k miles which equates on averaged about 5 years or so, thats only 3 dollars a year thats the price of a cup of coffee for just the assurance. If your not going to get the premixed one at least make sure you used distilled water and not water from your garden hose.
