Maximum Antifreeze: Reliable Protection Against Heat and Cold

When it comes to vehicle fluids, most drivers think of engine oil — but the coolant (antifreeze) is just as vital. It keeps your engine running smoothly in both hot and cold conditions while preventing corrosion and overheating.

Maximum™ Antifreeze products are engineered with advanced G11 and G12+ formulations to provide long-term, dependable protection against temperature extremes and corrosion.

What Is Antifreeze and Why Does It Matter?

Antifreeze (coolant) is a mixture of monoethylene glycol, water, and special corrosion inhibitors. Its main functions include:

• Preventing freezing in low temperatures
• Absorbing and transferring heat to prevent overheating
• Protecting metal components from corrosion, rust, and scale build-up

However, not all coolants are the same. The difference between G11 and G12 coolants lies in their chemical technology and durability.

G11 vs. G12: Chemistry and Performance

Maximum™ Antifreeze G11 Concentrate

View Product →

• Technology: Inorganic Additive Technology (IAT) – based on silicates, phosphates, and borates
• Color: Blue/green
• Compatibility: Older European, Japanese, and Korean vehicles
• Corrosion Protection: Excellent for aluminum, copper, and brass components
• Recommended Interval: 2–3 years or 60,000 km

Maximum™ G11 is a universal antifreeze suitable for traditional cooling systems — a cost-effective and reliable protection for older engines.

Maximum™ Antifreeze G11 Ready Mix -40°C

This ready-to-use formula, based on IAT technology, delivers excellent corrosion protection and consistent cooling performance. With a freezing point of -40°C, it’s ideal for cold-weather regions.

Maximum™ Antifreeze G12+ Concentrate

View Product →

• Technology: Organic Acid Technology (OAT) – free from silicates, phosphates, amines, and nitrites
• Color: Red/pink
• Compatibility: Modern aluminum radiator systems (VW, Audi, Mercedes-Benz, GM, and Japanese vehicles)
• Service Life: 5+ years or up to 250,000 km
• Advantages: Excellent heat transfer efficiency and minimal maintenance

Unlike G11, G12+ antifreeze only activates where corrosion begins, ensuring longer life and better thermal performance.

Maximum™ Antifreeze G12+ Ready Mix -40°C

This ready-mix formula combines demineralized water and ethylene glycol with advanced inhibitors, ensuring stability and reliable protection down to -40°C. It’s specially designed for hot and cold climates — from GCC deserts to European winters.

Key Benefits of Maximum™ Antifreeze

1. Corrosion and rust protection – Tested according to ASTM D1384 standards.
2. High thermal stability – Performs under extreme heat and pressure.
3. Long service life – G12+ lasts up to 5 years or 250,000 km.
4. Material compatibility – Safe for aluminum, copper, and steel systems.
5. Flexible use – Available in both Concentrate and Ready Mix options.

Which Antifreeze Should You Choose?

• Choose G11 if:
  • Your vehicle was manufactured before 2001
  • You use traditional copper or brass radiators
  • You want a universal, cost-effective solution
• Choose G12+ if:
  • Your vehicle was built after 2001
  • It has a high-efficiency aluminum radiator
  • You prefer long-life coolant with minimal maintenance

Note: Never mix G11 and G12+ coolants — their chemical bases differ and may destabilize when blended.
