Didn't work!
Dumped this in my Humvee pressurized coolant reservoir and it didn't lower temps at all. It has a hydraulic fan that turns on like clockwork at a specific point in my commute, so even a 5* drop in temp would be noticeable. Zero change after driving for a week. It might be better if I ran just this with distilled water. Also, smells like urine.

It works!
Texas heat forced me to try this out. I flushed my system and did a 90/10 mix and the results are great. It keeps my truck running cool no matter how hard I push her.

Not sure the results are worth the expense.
No real noticeable temperature difference on my Dodge Diesel.
