Greyhound Coolant / Antifreeze OAT G12 EL 25 Blue 500ml
Greyhound Coolant / Antifreeze OAT G12 EL 25 Blue 500ml is a ready-mixed anti-freeze & summer coolant — OAT G12 coolant pre-diluted 25/75 with deionised water. Specifically, it gives everyday top-ups real protection: corrosion inhibitors, water pump lubrication and boil-over resistance at an everyday price.
Because plain water protects nothing and dilutes the inhibitors already in your system, every water top-up weakens your coolant. Moreover, many cheap “summer coolants” are little more than coloured water. In contrast, Summer Mix carries genuine silicate-free OAT G12 chemistry in every litre.
Real Summer Coolant, Not Coloured Water
For example, this 500ml is the smart replacement for the water bottle in your boot. In addition, it suits petrol and diesel engines alike. As a result, warm-climate motorists protect their cooling systems affordably. Therefore, for inland winters or heavy towing, step up to our RTU 50/50 for –37°C protection.
