I'd follow along with JW's line of thought. Water has better heat transfer properties than ethylene or propylene glycol so in order to maximize your cooling system efficiency for the best cooling, you only want enough antifreeze present for your expected lowest temperatures, plus a little extra for a safety margin. If the amount is very small or none, then add a can of corrosion inhibitor.
