I wanted to let you all know that I added Royal Purple "Purple Ice" to my radiator coolant the other day. I will not try to tell you how much it improved my horsepower or any BS like that. I will tell you for nine bucks it was worth it to me. What it does "It reduces engine heat by reducing the surface tension of the radiator fluids for improved heat transfer" so it is supposed to help make your car run a little cooler.
