So for shits and giggles, put a pot on the stove filled with distilled water, raise the temp to 180 degrees then pour in some WW. Does the temp change? |

It's a well-known fact, not unknown, that 100% water has more specific heat than 50% water/50% ethelyne glycol. So presumably if water wetter lets you safely run almost 100% water (3 gallons of water, 12 ounces of WW or whatever) then your cooling system will be more efficient. I've never used the stuff though. The main reason is that I've never needed to. My Z can maintain it's desired temperature just fine. I've never had it happen that the fans kicking on could not bring the temperature down. So the heat transfer ability of the coolant is not a problem. And 50/50 coolant has a huge body of data surrounding it in terms of its affect on engine life, water pump life, etc. There is little risk in using it. Water Wetter on the other hand, who knows. Plus, Water Wetter, as you are only using a small amount, couldn't possibly alter the freezing or boiling points of the water as much as a 50% additive could. And I drive my car year 'round. So using 50/50 coolant is a no-brainer. If you are having some issue with cooling capability, I would suggest troubleshooting the system and fixing the issue rather than changing coolants as the initial approach. ![]()

I noticed 0 difference except a lighter wallet. Drained the stuff out and put coolant back in.
