An Additive That Reduces Engine Temperatures
To fine-tune the new Dominator Coolant Boost formulation, extensive dyno testing was performed by AMSOIL. An engine was run at 4500 rpm until a steady coolant temperature was reached. Straight water leveled off at 220°F, while a mix of 50-50 antifreeze and water had a baseline temperature of 228°F. The chart below shows the amount of temperature reduction when AMSOIL Dominator Coolant Boost was added.

| 50-50 Antifreeze Mixture W/Dominator Coolant Boost | 8°F | ||||
| Straight Water W/Dominator Coolant Boost | 25°F |
Reduces Cold Weather Warm-up Times
AMSOIL’s exclusive surfactant technology not only works at high temps, it also dramatically reduces winter warm-up periods. When coolant temperatures reach 120°F, the vehicle’s occupants start to feel warmth from the heater system. The surfactants in AMSOIL Dominator Coolant Boost improve heat transfer over regular 50-50 antifreeze mix. Engines with 50-50 antifreeze mix treated with the prescribed dosage of AMSOIL Dominator Coolant Boost reach an operating temperature of 120°F 54% faster than engines using regular 50-50 antifreeze mix.
| Engine Warm-Up Reduction Times | -1°C to 49°C | -1°C to 82°C | |||
| 50-50 Antifreeze Mixture | 6 min 18 sec | 11 min 18 sec | |||
| 50-50 Antifreeze Mixture W/ AMSOIL Coolant Boost | 3 min 12 sec | 5 min 18 sec |
Why You Shouldn’t Use Only Straight Water in Racing Engines
A common practice in race cars and vehicles operated in hot climates is to use straight water in the cooling system. The problem with using straight water as a coolant is its corrosive effects. Corrosion can congest cooling systems and damage water pumps. Adding AMSOIL Dominator Coolant Boost neutralizes the corrosive effects of straight water.
In independent trials using the standardized ASTM D1384 testing protocol, AMSOIL Dominator Coolant Boost was tested against straight water on a number of common engine and radiator materials. The values below represent weight “in milligrams” lost to corrosion.
| Metal | Straight Water | Water with Coolant Boost | |||
| Copper | 25mg | 1mg | |||
| Solder | 62mg | 1mg | |||
| Brass | 23mg | 0mg | |||
| Steel | 18mg | 1mg | |||
| Cast Iron | 29mg | 0mg | |||
| Cast Aluminum | 91mg | 0mg |
Independent Comparison: AMSOIL Dominator Coolant Boost versus Red Line Water Wetter
A common additive used by high performance enthusiasts is Red Line Water Wetter. Although these two products perform similar tasks, the AMSOIL coolant additive uses a surfactant formula that takes effect during cold starts and keeps working right through to maximum temperature. The Red Line product works only during high operating temperatures. The advantage of this is that AMSOIL Dominator Coolant Boost decreases warm-up times and stabilizes temperatures from warm-up through to the engine’s upper temperature limits.
AMSOIL Dominator Coolant Boost offers improved corrosion protection and lower operating temperature over Red Line Water Wetter. In independent, head-to-head testing, AMSOIL Dominator Coolant Boost and Water Wetter were tested for corrosion using common engine and radiator materials. The values below represent weight “in milligrams” lost to corrosion using the ASTM D-2570 “Simulated Service” testing protocol. Both products were mixed with straight water at the prescribed mix rate.
| Metal | Red Line Water Wetter | AMSOIL Dominator Coolant Boost | |||
| Copper | 6mg | 7mg | |||
| Solder | 25mg | 0mg | |||
| Brass | 5mg | 3mg | |||
| Steel | 4mg | 0mg | |||
| Cast Iron | 2mg | 0mg | |||
| Cast Aluminum | 34mg | 0mg |
AMSOIL Dominator Coolant Boost also delivered lower operating temperatures versus Red Line Water Wetter. Testing was conducted on actual engines using straight water and 50-50 antifreeze blend.
| Coolant Type | AMSOIL Dominator Coolant Boost | Red Line Water Wetter | |||
| 50-50 Antifreeze Mixture | 8°C | 3.24°F | |||
| Straight Water | 25°F | 12°F |
Suitable Applications for AMSOIL Dominator Coolant Boost
