Granville Sub Zero Universal RTU Antifreeze

Granville Sub Zero Universal uses OAT additive technology and is free from nitrites, amines, phosphates, borates and silicates and will provide effective protection for 5 years or 150,000 miles (whichever is the sooner). 

If this product is mixed with traditional coolant technology it should be assumed that the service life will be that of the traditional coolant.
