Greyhound Coolant / Antifreeze OAT G12 EL 80 Blue 1L
Greyhound Coolant / Antifreeze OAT G12 EL 80 Blue 1L is a high-strength extended life coolant pre-blend on silicate-free Organic Acid Technology (OAT G12) — 80% coolant already blended with deionised water. Specifically, it gives workshops near-full-strength antifreeze that dilutes faster and more accurately than neat concentrate.
Because the first dilution is factory-done with deionised water, there is less risk of hard-water scale at mixing time. Moreover, the OAT G12 inhibitors are free of silicates, nitrites, amines, phosphates and borates, so the cooling system stays clean and protected through an extended service interval.
High-Strength OAT G12 Protection, Your Ratio
For example, buyers who reach for “96%-style” high-strength antifreeze get a cleaner, modern alternative here. In addition, the same extended-life organic inhibitors protect aluminium, cast iron, steel and brass. As a result, it suits petrol and diesel engines in passenger and light commercial vehicles alike. Therefore, one pack covers a season of mixing.
Key Features:
- High-strength 80% OAT G12 extended life pre-blend
- Silicate-, nitrite-, amine-, phosphate- and borate-free
- Faster, safer dilution — first blend done with deionised water
- Extended drain intervals compared to G11 antifreeze
- Protects aluminium, copper, cast iron and soldered joints
- 1L bottle for precise DIY mixing
Technical Specifications:
- G12 extended-life OAT
