50% full strength antifreeze & 50% distilled is what is USUALLY recommended….. At my business I always aimed for 66% full strength antifreeze & the rest distilled water….. And people always seem to forget that there is ALWAYS some of the old “stuff” left behind in the cooling system ( hoses, engine block, heater, etc ) unless it’s flushed out…. And if you do a good job of flushing then you have some leftover water in your system…. How much is left over in your system???
I do have a concentration checker and I do plan to err on the high side. I don't have chlorine in my water so it is not as corrosive as most tap water. One of the benefits of being on a well. My water heater has been in use for 23 years with no issues.
