There are many claims to what is best.
I can give you my own (semi-scientific) experience with different combinations. After the building of my engine, and not having my car here yet all I had in my garage was my engine on a test stand.
During that month I must have run 15-20 gallons of fuel through that thing. Checking for leaks, tweaking and sometimes just playing. The poor engine almost needed a set of rings before it got put in the car.
During that time I changed the
oil and the coolant often.
I tried 50-50. I tried 50-50 with water wetter. I tried water only. I tried water with only water wetter.
Considering the ambient temperatures in my garage, and air flow etc. The experiment was held in a very consistent setting with no variables. No air flow, no variation in the ambient temperature etc.
The claims of Water Wetter were confirmed.
Just Water Wetter with Water-NO
ANTIFREEZE- consistently gave better results.Almost 20 degrees cooler.
That would be my recommendation.
