Our Expert Verdict: antifreeze

AI
For most drivers, a reputable ready-to-use OAT coolant provides the best balance of convenience and engine safety, eliminating the risk of incorrect dilution ratios.

Market Overview: antifreeze

AI
The market is shifting toward long-life organic acid technology (OAT) coolants that offer extended protection intervals compared to traditional inorganic formulas.

Buying Guide: antifreeze

AI
When selecting a coolant, prioritise compatibility with your engine's metallurgy and the choice between a pre-mixed solution or a concentrated formula.

Selection Criteria

Products were selected based on verified user ratings, volume-to-price value, and documented corrosion protection longevity.

Budget Advice

AI
Entry-level options are typically small top-up bottles, while mid-range and premium options offer larger bulk volumes or specialised long-life chemical additives.

Conclusion: antifreeze

AI
Protecting your engine from extreme temperatures is a small investment that prevents costly mechanical failures. Take a closer look at our full list to find the specific formulation and volume that fits your vehicle's needs.

Frequently Asked Questions

AI
Generally, no. Different colours often indicate different chemical bases (such as IAT, OAT, or HOAT). Mixing them can lead to chemical reactions that cause the coolant to gel, potentially blocking your cooling system and overheating the engine.
Concentrates must be diluted with distilled or demineralised water to reach the desired freeze-protection level. Ready-to-use (RTU) versions are pre-mixed, offering convenience and ensuring the ratio is correct for immediate topping up.
While some modern long-life coolants can last several years, most manufacturers recommend a flush and replacement every two to five years. Check your owner's manual for the specific service interval of your vehicle.
