Royal Purple® Purple Ice®

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:
• Reduces coolant surface tension to allow greater heat transfer, resulting in lower coolant temperatures
• Reduces hot spots in the engine and cylinder heads, reducing the possibility of engine failure
• Helps prevent overheating, keeps the system clean and extends the life of the water pump
• Purple Ice is safe to use with water-only or antifreeze / water blends• Purple Ice is compatible with OEM and stock replacement coolants, including extended-life antifreezes
• Purple Ice does not contain glycol and is safe and legal for track use

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.
