You don't need antifreeze in FL. As Petehovie recommended, norosion and Reverse Osmosis water, not tap. RO water sold in gallons for drinking in Walmart. RO has no additives or trace minerals in it like distilled or spring water. Although anti-freeze may have a little higher boiling point, the benefit of running straight water w/norosion is water is a better heat conductor, so your engine runs cooler than with antifreeze.
