Greyhound Coolant / Antifreeze OAT G12 EL 50 Yellow 20L
Greyhound Coolant / Antifreeze OAT G12 EL 50 Yellow 20L is our 50/50 ready-to-use extended life coolant on silicate-free Organic Acid Technology (OAT G12), in yellow — the colour common to universal coolants and colour-coded mixed fleets. Specifically, it keeps fleet identification consistent while upgrading every cooling system to G12 extended life protection.
Because corrosion and cavitation damage modern aluminium cooling systems, extended-life organic inhibitors act directly at corrosion sites. Moreover, the formula is free of silicates, nitrites, amines, phosphates and borates, so radiators stay deposit-free and heat transfer stays efficient for the full extended interval.
Yellow OAT G12 Coolant for Mixed Fleets
For example, a 20L drum gives every vehicle in the fleet an identical, correct fill — no mixing station, no ratio drift. In addition, it suits petrol and diesel engines alike and lubricates the water pump. As a result, motorists and fleets get correct protection from the first cold start. Therefore, you simply fill up and drive.
Key Features:
- Yellow-dyed OAT G12 extended life coolant for colour-coded fleets
