Summer Water Temp Baseline?

I didn't say anything was wrong with it cuz I have no personal experience with it I just thought I read some bad reviews on it. It could have been on something else because I was just reaching myself for a better way one day..
I ended up getting a bigger bottle of wetter type stuff, that`s label read the same as puple ice, but was 4 more oz. of it for $3 cheaper . Started the engine and circulated it , but didn`t drive it .
I did find that my recovery system was empty for the first time , I think I might have had trapped air in it !!
