You don't have too worry too much as long as your have enough antifreeze to protect from boilover (in my case, freezing point isn't a huge concern and almost any amount of antifreeze will do for where I live). As long as I keep it changed regularly, rust,etc. won't be a worry either.


You know what they say about "assume"? ;-)
Since the boiling point is directly dependent on the mixture (%/ratio) of H20 and coolant, I believe it makes sense to know this data. I desire maximum benefit/maximum boiling point. I suspect you are correct in that you started with a 50/50 mixture (mixture still able to prevent boilover in Ga. this time of the year), I just don't like leaving things to chance or guess work. Hard, fast data is easier to work with, for me. I then record this info into a program that tracks all vehicle preventative maintenance and repair. Of course each to his own in the area of preventative maintenance.
