PEAK OET Extended Life Blue 50/50 Antifreeze/Coolant 1 Gal — POAT Prediluted for Asian Vehicles

PEAK OET Extended Life Blue 50/50 is a ready-to-use, phosphate-enhanced POAT antifreeze/coolant formulated for many Asian vehicles to protect cooling systems from corrosion and provide extended service life.

This 1-gallon prediluted coolant is tailored for vehicles that specify a blue, phosphate-enhanced Organic Acid Technology (POAT) formula—commonly required by Acura, Honda, Infiniti, Mitsubishi, Nissan, Subaru, and Suzuki. It arrives premixed 50/50 with high-quality water so you can top off the radiator or perform a quick flush-and-fill without measuring concentrates. The advanced corrosion inhibitors help safeguard pumps, radiators, and engine passages, while a bittering agent (Denatonium Benzoate) discourages accidental ingestion.

Which vehicles is this coolant made for?

PEAK OET Blue 50/50 is developed specifically for many Asian makes that call for a phosphate-enhanced POAT formula. Check your owner's manual for coolant color and specification notes to confirm compatibility before use.

• Recommended for Acura, Honda, Infiniti, Mitsubishi, Nissan, Subaru, and Suzuki models
• Meets requirements where a blue, phosphate-enhanced POAT antifreeze is specified
• Compatible with other extended life antifreeze/coolants when mixed according to guidelines

How do I use the 50/50 prediluted formula for topping off or a flush?

Because the product is already mixed 50/50 with water, it’s ready for immediate use for top-offs and makes a flush-and-fill job faster. For a full coolant change, perform a complete system flush as recommended, then pour the 50/50 solution until the system reaches the proper fill level.

• Top off the radiator or overflow reservoir directly—no mixing required
• For a flush-and-fill, drain old coolant, flush system, and refill with this 50/50 solution
• Follow vehicle manufacturer instructions and disposal regulations for used coolant

What protection and service life can I expect?

PEAK guarantees up to 150,000 miles or 5 years of service life when installed as part of a complete flush and fill, helping reduce the frequency of coolant service under normal driving conditions. The formula focuses on preventing rust and corrosion to prolong component life, though service intervals depend on driving habits and vehicle conditions.

• Formulated to inhibit rust and corrosion across cooling system components
• Extended service life: up to 150,000 miles / 5 years when installed per instructions
• Contains bittering agent Denatonium Benzoate to deter accidental ingestion

Is this coolant safe to mix with other antifreeze types?

This coolant is fully compatible with other extended life antifreeze/coolants of similar POAT or specified technologies, but mixing different chemistries or colors without checking compatibility can reduce performance. When in doubt, perform a complete flush and refill to avoid contamination of inhibitor packages.

• Compatible with other extended life POAT-type antifreezes when mixing is appropriate
• A full system flush is recommended before switching coolant chemistries
• Always follow manufacturer coolant specifications to preserve warranty and performance

Who is this for: PEAK OET Extended Life Blue 50/50 is designed for vehicle owners and service technicians who need a convenient, ready-to-install antifreeze for Asian-brand cars and SUVs that require a blue, phosphate-enhanced POAT coolant. It’s a good choice for DIYers doing routine top-offs, shops completing flush-and-fill services, and anyone looking for extended protection with a premixed option that removes the guesswork of diluting concentrates.
