Greyhound Coolant / Antifreeze OAT G12 EL 100 Blue 500ml
Greyhound Coolant / Antifreeze OAT G12 EL 100 Blue 500ml is a extended life coolant concentrate built on silicate-free Organic Acid Technology (OAT G12). Specifically, you dilute it with deionised water to the exact protection your climate needs, so this 500ml bottle blends up to a litre of 50/50 coolant for precise top-ups.
Because corrosion attacks modern aluminium cooling systems, the OAT G12 formula uses extended-life organic inhibitors that act directly at corrosion sites. Moreover, it is free of silicates, nitrites, amines, phosphates and borates, so radiator passages stay clean and heat transfer stays efficient for the full extended service interval.
Extended Life OAT G12 Concentrate Protection
For example, 1 litre of concentrate with 1 litre of deionised water protects to –37°C. In addition, a 33% mix protects to –18°C for mild coastal winters, while 60% reaches –52°C. As a result, one antifreeze concentrate suits petrol and diesel engines across passenger cars, SUVs, bakkies and light commercials. Therefore, workshops control strength and cost precisely.
