Millers Oils continue their highest quality range with an ethylene glycol based antifreeze and coolant mix with features OAT (organic acid technology).The Millers Anti Freeze is designed to be diluted with water for engine cooling systems in cars, vans, trucks and other heavy duty machinery with corrosion inhibitors and frost protection. Red in appearance it differs to the traditional blue mixture by increasing corrosion protection and durability, although it does not protect to the temperature drop of the blue.The Anti Freeze can be used in systems right down to minus 37 degrees celcius depending on ratio mix with examples of:33% volume in water providing pumpability down to -20C50% volume in water providing pumpability down to -37COAT (organic acid technology) enables coolant systems to resist corrosion for longer periods and to a greater extent with typical usage periods up to 150,000 miles or 5 years, meaning fewer system changes.The Millers anti freeze is free from:SilicatesNitrat
