i just watched them test this on horsepower tv this morning. from their results at operating temp and idle it stayed around 10-15 degrees cooler and same as for a drive. they simulated the drive on their dyno i cant remember how long of a drive but it was supposed to be as if you were driving up hill for 20 miles or 20 minutes i cant remember exactly. but it stayed 10-15 degrees cooler as well. these tests were all done with straight water in the radiator and 2 bottles of that royal purple ice additive. seems like it works!!

If you try it....use the two bottles of RP Ice.....half jug of whatever coolant you like......the rest water.

It probably works.

I heard that if you pee in the radiator, the same thing happens.

As sjsingle1 points out, there are more reliable mechanical methods to bring the temperature down.
