AMSOIL Antifreeze and Coolant Boost


Dominator Coolant BoostAMSOIL Dominator Coolant Boost

Formulated with proprietary tiered surfactant technology, providing quick and effective heat transfer inside radiator and cylinder heads, which results in reduced operating temperatures, more efficient operation, increased horsepower and significantly reduced engine warm-up times in cold weather. It also contains a robust mixture
of corrosion inhibitors that protect the radiator, heater core, water pump, cylinder heads, engine block and intake manifold from the damaging effects of corrosion. More Info

Propylene Glycol Antifreeze and Engine CoolantAMSOIL Propylene Glycol Antifreeze and Engine Coolant

Super long life fluid - 750,000 miles/7 Years of service in over-the-road trucks & 250,000 mile/7-Year service life in light-truck and auto applications. Essentially nontoxic & biodegradable. Superior performance in all climates. Contains corrosion inhibitors & anti-foam agents.


Propylene glycol may also be used in antifreeze coolant mixtures and provides good high- and low-temperature radiator protection. Propylene glycol, which smells and tastes bland, is significantly less toxic than ethylene glycol is. In fact, propylene glycol is available in food and pharmaceutical grades for use in human foods and medications and in grades appropriate for use in pet foods.


Compared to ethylene glycol products, propylene glycol products appear to provide equal, or in some instances, superior protection against corrosion and erosion in diesel engines, which are more prone to both types of damage than are gasoline engines.


When engine oil is contaminated by coolant, bearing damage occurs at a lower concentration with ethylene glycol than it does with propylene glycol; 1 percent ethylene glycol in the engine oil may lead to bearing damage. Bearings treated to 8 percent propylene glycol contamination of the engine oil remained undamaged.


Finally, while both ethylene glycol and propylene glycol biodegrade at about the same rate, propylene glycol's lower toxicity makes it environmentally less hazardous during the biodegradation process. AMSOIL ANT is silicate and phosphate-free and formulated for use in gasoline engines, light-duty diesel engines and heavy-duty diesel engines. Some other propylene glycol products do not contain an additive system appropriate for use in heavy-duty diesel engines.

Dominator Coolant BoostAMSOIL Dominator® Coolant Boost is designed to reduce corrosion and significantly enhance heat transfer in cooling systems. One of the overlooked benefits of better heat transfer is much quicker engine warm-up in winter conditions, which is noticed when the vehicle's defroster works much sooner.


To understand how Dominator Coolant Boost reduces engine warm-up times in cold weather, it is imperative to understand the fundamentals of an engine's cooling system and how Coolant Boost's proprietary tiered-surfactant technology works. The same tiered-surfactant technology that aids in reducing engine operating temperatures also decreases engine warm-up times.


In a vehicle's cooling system, the ultimate goal is to quickly and effectively move heat away from engine components, permitting the engine to run at a safe, controlled temperature. An effective cooling system reduces stress on all aspects of the engine, including the lubricating oil. Alternatively, a corroded cooling system that transfers heat ineffectively will eventually lead to engine overheating, breakdown of engine oil and catastrophic failure.


Before studying tiered surfactants, it is important to understand what a surfactant does in a cooling system. A surfactant reduces the surface tension of water and antifreeze, allowing closer contact with metal parts. This closer contact increases the coolant's effi ciency in transferring heat away from hot engine parts and out through the radiator and fan.


Many leading coolant additives contain only one surfactant, limiting their temperature ranges and ultimate effectiveness. AMSOIL Dominator Coolant Boost uses three surfactants, each designed to operate in a different temperature range to increase liquid-to-metal contact from the time the vehicle starts to the time it reaches operating temperature.


Graphic A (below) illustrates how each surfactant in Coolant Boost's tieredsurfactant technology is designed to provide optimal performance over a wide temperature range, while competing products with only one surfactant are limited to performance in a single temperature range.


Graphic B (below) outlines controlled testing of AMSOIL Dominator Coolant Boost with a 50/50 antifreeze/water mix. When a cooling system reaches 120°F, the operator typically feels warm air coming out of the defroster. The time it takes to reach this temperature with Coolant Boost is reduced by 45 percent compared to the 50/50 antifreeze/water mix alone.


Through the use of tiered surfactants, AMSOIL Dominator Coolant Boost delivers quicker warm-up times in the winter and reduced engine temperatures in the summer, making it an excellent choice for year-round use.
