Cooling

I currently use Engine Ice. I've used the factory fill, Engine Ice, and straight distilled water with water wetter added. Monitoring coolant temps, there's very little difference in the three, with a slight advantage to straight water. Not having to worry about freezing I'd probably stuck with that but a local dealer suggested Engine Ice and I've run it for a couple of years.
 
THanks BB last time i changed my antifreeze was 2007, i've always checked the overflow to make sure there was some antifreeze in the radiator. I've never had a problem with the antifreeze i'm using. When i see a coolant thread it reminds me of the last time i changed it.
