Tire & Oil
Antifreeze/Coolant Grades
Common Color: Green
Target Vehicles: Older cars (typically pre-mid-1990s) with cast-iron engines and brass/copper radiators.
Lifespan: Short; needs replacement every 2 years or 36,000 miles.
Properties: Uses silicates and phosphates to provide fast-acting protection against rust and corrosion.
Common Colors: Orange, Red, Pink, Blue, or Purple
Target Vehicles: Modern vehicles (like GM's Dex-Cool or VW/Audi specs) with aluminum engines and cooling components.
Lifespan: Long-life/Extended-life; typically lasts 5 to 10 years or up to 150,000 miles.
Properties: Silicate- and phosphate-free. It relies on organic acids to form a slow-acting but highly durable molecular shield against corrosion.
Common Colors: Yellow, Gold, or Turquoise
Target Vehicles: Many newer domestic, European, and Asian vehicles.
Lifespan: Extended-life; around 5 years or 50,000 to 150,000 miles.
Properties: A blend of IAT and OAT. It uses a small amount of silicates or phosphates for immediate metal protection alongside organic acids for longevity.
Freeze Protection: Down to approximately -34°F (-37°C).
Boil-Over Protection: Up to about +265°F (129°C). [1]

1. Inorganic Additive Technology (IAT)
Common Color: Green
Target Vehicles: Older cars (typically pre-mid-1990s) with cast-iron engines and brass/copper radiators.
Lifespan: Short; needs replacement every 2 years or 36,000 miles.
Properties: Uses silicates and phosphates to provide fast-acting protection against rust and corrosion.
2. Organic Acid Technology (OAT)
Common Colors: Orange, Red, Pink, Blue, or Purple
Target Vehicles: Modern vehicles (like GM's Dex-Cool or VW/Audi specs) with aluminum engines and cooling components.
Lifespan: Long-life/Extended-life; typically lasts 5 to 10 years or up to 150,000 miles.
Properties: Silicate- and phosphate-free. It relies on organic acids to form a slow-acting but highly durable molecular shield against corrosion.
3. Hybrid Organic Acid Technology (HOAT)
Common Colors: Yellow, Gold, or Turquoise
Target Vehicles: Many newer domestic, European, and Asian vehicles.
Lifespan: Extended-life; around 5 years or 50,000 to 150,000 miles.
Properties: A blend of IAT and OAT. It uses a small amount of silicates or phosphates for immediate metal protection alongside organic acids for longevity.
Why is 50/50 the "Gold Standard"?
A true 50/50 blend strikes the perfect balance for your cooling system. Contrary to intuition, 100% concentrated antifreeze performs worse on its own. It actually freezes at a higher temperature than a 50/50 mix and cannot efficiently transfer heat away from the engine.
When properly pressurized by your vehicle's radiator cap, a 50/50 ethylene glycol mixture provides:
Freeze Protection: Down to approximately -34°F (-37°C).
Boil-Over Protection: Up to about +265°F (129°C). [1]
