Engine Ice hi-performance coolant is biodegradable, phosphate free and non-toxic, typically reduces operating race temperatures and effectively keeping boil over temperatures to 256° Fahrenheit or less and freeze-up protection to -26° Fahrenheit | With an average reduction in operating temperatures of 10° Fahrenheit - 20° Fahrenheit Engine Ice is perfect for racing or street, motorcycle or auto, ATV or snow machine | Engine Ice hi-performance coolant is legal in CCS and ASRA road racing and permitted at many tracks around the world. Easy to Use – Premixed with deionized water for out-of-the-bottle use. | Engineered to keep your operating temperatures at optimum performance to not lose power through excess heat; Engine Ice is safe for aluminum and most all metals | Uses propylene glycol, which has been proven to eliminate water pump gasket and seal failures; it has also shown in high load, high stress conditions to reduce operating temperatures more than standard coolants
