Royal Purple Purple IceCooling System Optimizer Antifreeze & Coolant, 12 oz

Royal Purple Purple Ice is a high performance radiator conditioner. Its advanced 2-in-1 corrosion inhibitor and wetting agent provides year-round defense against corrosion and reduces the surface tension of the radiator coolant to help reduce engine temperatures. REDUCED COOLANT TEMPERATURES Extensive testing confirms Purple Ice reduces coolant temperatures better than comparable products while providing extra corrosion protection. For example, the average operating temperature of a 350 c.i.d. V8 engine (equipped with 160˚ thermostat) when dyno-tested with different coolants are: A. Standard mix of water and glycol (antifreeze) — 228˚F B. 50/50 water/glycol mix with Purple Ice added — 222˚F C. Straight water (no corrosion protection) — 220˚F D. Water with Purple Ice added — 200˚F RECOMMENDED TREAT RATE* - For use with 50/50 antifreeze / coolant mixture: 1 oz. / quart of cooling system capacity - For use with straight water or higher water percentage antifreeze / coolant mixture: 2 oz. / quart of cooling system capacity - Minimum of 20% antifreeze is recommended in street-driven vehicles. Purple Ice does not provide freeze protection. Use an appropriate amount of antifreeze for the cold temperatures in your area.
