Have you run AF in a loop before? I get the distinct impression you haven't.
No I have not.
When I considered it I sat down and read about it for several hours and concluded it was a bad idea, and I trust that reading WAY more than I do anyone's anecdotal experiences on a forum.
I can't remember my exact sources (it has been a while now) but I think I started with the Overclockers.com water loop chemistry guides parts 1 & 2 and then further read up on all the additive chemicals meantioned there, including manufacturers application guides, and various chemical engineering articles I could find.

I got pretty into the weeds on the subject matter, and I am very comfortable with my conclusions, which were along the lines of "automotive antifreeze is suboptimal at best from a viscosity and thermal transfer perspective, and may provide inadequate corrosion protection depending on the brand of the anti-freeze, it's concentration, and the design particulars of the loop and water components."
I'm well aware that lots of people have used it - especially back in the day - and claim to have had great results, but I also keep hearing people complaining of corrosion, and when they do it's never "damn, maybe I used an improper coolant". Instead it's always "point the finger at the manufacturer of the block".
