Opticool Antifreeze Universal (Clear) is a monoethylene glycol based ready-to-use engine coolant which uses Organic Acid Inhibitor Technology and is free from nitrites, amines, phosphates, borates and silicates (BTC Classification Type 4E). The additive package has been specifically formulated to provide excellent continued corrosion protection for all types of engines under the most demanding conditions.

Testing has shown that Opticool Antifreeze Universal (Clear) provides good corrosion protection to all the components found in modern engines. Unlike traditional coolants which employ inorganic inhibitors, Opticool Antifreeze Universal (Clear) has excellent hard water stability and very low inhibitor depletion rates. It has been extensively tested and shown to be compatible with other monoethylene glycol based coolants and can be safely mixed with them. If Opticool Antifreeze Universal (Clear) is used in combination with traditional coolant technology it should be assumed that the service life will be that of the traditional coolant.
