Those looking for a cooler running car should check out Hyper Cool by Appled Chemical Inc. which is an antifreeze replacement/enhancer. It is an anti corrosion/water wetter in one product. I swapped out the coolant in my car and am more than satisfied with the results. Running in my garage with the A/C, the car had difficulty keeping the 185 degree thermostat open. Check out their website (especially the FAQ section: www.norosion.com
If you have any questions, Email me. I'm not a chemist but have learned a lot from the manufacturer about cooling systems and coolants since becoming the Hawaii distributor.
This company actually makes "Purple Ice" for Royal Purple but the product that they market is superior to it.
