Greyhound Coolant / Antifreeze OAT G12 EL 25 Blue
Greyhound Coolant / Antifreeze OAT G12 EL 25 Blue is a ready-mixed anti-freeze & summer coolant — 25% OAT G12 coolant pre-diluted with 75% 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, one 5L keeps a household’s cars topped up for months in coastal KZN, the Lowveld or the Cape. 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.
