WARM UP YOUR VEHICLE FASTER IN COLD WEATHER

AMSOIL DOMINATOR® Coolant Boost (RDCB) 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’s important 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 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 oil. Alternatively, a corroded cooling system that transfers heat ineffectively will eventually lead to engine overheating, motor-oil breakdown and catastrophic failure.

A surfactant reduces the surface tension of water and antifreeze, allowing closer contact with metal parts. This closer contact increases the coolant’s efficiency 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 effectiveness.

AMSOIL DOMINATOR Coolant Boost uses three surfactants, each designed to operate in a different temperature range to increase liquid-tometal contact from the time the vehicle starts to the time it reaches operating temperature.

How it improves both warm and cold temperature issues

Graphic A illustrates how each surfactant in Coolant Boost’s tiered-surfactant 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 outlines controlled testing of AMSOIL DOMINATOR Coolant Boost with a 50/50 antifreeze/water mix. When a cooling system reaches 120°F, you feel warm air coming out of the defroster. The time it takes to reach this temperature with Coolant Boost is reduced by 49 percent compared to the 50/50 antifreeze/water mix alone. The time required to warm the cooling system to 180ºF is reduced by 54 percent.

For updated test data please refer to the online data sheet.

 

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.

  • Helps vehicles warm-up an average of 54% faster in winter.
  • Reduces engine temps up to 25˚F in summer.

Reviews

Me – Synthetic Warehouse:

When I had my AMC Eagle with the inline six. The carbureted intake was off to the side of the engine. South Dakota temperatures made it nearly impossible to get heat to the carb.  Using the coolant boost I was able to cut the warm-up time from 12 minutes to just over 6. The engine coolant runs just under the carburetor so this was critical!

Seems to be premium quality

Engine warms up faster in winter, and stays dead on thermostat temp during heat of summer (used to go up about 10 degrees idling with a/c on really hot days, which manual said was “normal”)
Good product

Product seems to be working. My temperature gage is showing 5 degrees cooler than it was running.
Great stuff Dominator coolant boost
By  MATT,  a  Verified Buyer  from  PA  on  December 20, 2021

Now that it is winter I did a quick spill and fill with Amsoil car and light truck coolant with half a bottle of this. Car heats up faster and stays cooler in the summer. It works.
Results are good although limited use to date

This is my first time to use Dominator Coolant Boost. In fact, the first time I have ever supplemented a coolant/water mix in over 40 years of car ownership. I recently acquired a 2016 Corvette Z06, a car known for overheating issues. I had the coolant replaced and had the shop add Dominator at that time. The initial returns are good, but based on very little true hard driving time. My comparison is the day of the service. I drove to the shop, about 30 minutes from my home by highway. The coolant temperature fluctuated above/below 200 degrees. Later in the day, taking the same roads but with a higher ambient outside air temperature, the car ran between 185 and 190 degrees. Definitely not a scientific testing method, but there was a difference.
It Works!

Every vehicle I used Coolant Boost in showed a noticeable difference in warm up time in cold weather. It gives me confidence that my engine is protected in hot weather.
Works as advertised.
By  BRIAN,  a  Verified Buyer  from  Western Colorado   on  August 17, 2021

I’m seeing a difference of 10-15 degrees cooler temperatures in a 1 ton dually. 96 degrees outside and climbing a 6 percent was usually 215. Barely gets over 200 now.
