How to Choose the Right Antifreeze: A Colour and Formulation Approach

When it comes to choosing the right antifreeze for your heavy-duty vehicles, colour and formulation can be useful indicators of the properties and technologies used in the product. Here’s a guide to help you navigate the options available:

• Green Antifreeze: Traditionally, green antifreezes use inorganic additives. They are often suitable for older vehicles and require more frequent changes, typically every two years or 50,000 km.
• Orange Antifreeze: Often combined with Organic Acid Technology (OAT), this antifreeze is designed to provide long-term protection against corrosion. It is ideal for modern vehicles and can last up to five years or 250,000 km.
• Yellow Antifreeze: Typically represents a hybrid antifreeze (HOAT), combining the benefits of organic and inorganic technologies. It provides long-lasting protection and is compatible with many engine types.
• Pink/Red Antifreeze: Often used in Asian or European vehicles, this type of antifreeze is formulated for specific engines. It is important to check compatibility with your engine before using.

Formulation: Concentrate vs. Pre-Mixed

• Concentrate Antifreeze: This type of antifreeze must be mixed with water before use, usually in a 50/50 ratio. This allows the mixture to be customized for specific climate conditions, but requires careful consideration to ensure the correct ratio.
• Pre-Mixed Antifreeze: Ready to use, this antifreeze is already mixed in the correct ratio with distilled water. It offers a convenient solution and eliminates the risk of mixing errors, making it ideal for quick and hassle-free use.

Tips for Choosing the Right Antifreeze:

• Check Your Vehicle Manual: The manufacturer's recommended color and formulation of the antifreeze is a good place to start.
• Consider the operating environment: In extreme conditions, an antifreeze with specific protection against freezing or overheating may be necessary.
• Compatibility: Ensure that the antifreeze you choose is compatible with your vehicles’ engine materials to prevent corrosion or other damage.

Using color and formulation as guides, you can more easily identify the type of antifreeze that best meets your fleet’s needs, while ensuring optimal protection and long-lasting performance.
