Temperature Reduction Dynamometer Test

Controlled engine dyno tests were used to measure reduction in engine operating temperature. These dyno tests were conducted using a 350ci Chevy engine with an aluminum block and cylinder heads. The engine was run at 4,500 rpm until stabilized coolant temperature was achieved. Of course in non-controlled situations results may vary.

Coolant Mixture Stabilized Coolant Temperature
Straight Water (with no corrosion protection) 221 degrees F
Water with AMSOIL Inc. Dominator Coolant Boost 202 degrees F

Questions and Answers:

What are the AMSOIL INC. recommendations when using straight water coolant?

When using straight water as a coolant, the most robust form is softened water because the softening process removes impurities and minerals from the water by exchanging them for more beneficial minerals. Unlike distilled water, softened water will not act as an electrolyte, thereby minimizing damage from electrolysis. Although softened water is preferred, Dominator Coolant Boost contains an advanced formula that allows use of low-quality water (i.e. well water in cooling systems without concern of damage or scale/deposit buildup). Distilled water is not recommended in straight water systems.

For long storage periods, should the coolant be drained and the system left dry?

No. AMSOIL INC. Dominator Coolant Boost provides long-term corrosion protection. Dominator Coolant Boost contains a premium ingredient that chemically removes dissolved oxygen from any type of coolant, reducing the possibility of corrosion.

How does Dominator Coolant Boost prevent electrolysis and galvanic corrosion?

Galvanic corrosion occurs when antifreeze acts as an electrolyte between dissimilar metals in cooling systems. Dominator Coolant Boost contains a premium ingredient called molybdate, which forms a film on the surface of aluminum, controlling the transfer of electrons. This film helps minimize the tendency for electrolysis and galvanic corrosion.

Is Dominator Coolant Boost compatible with stop-leak additives?

There are no known compatibility issues between Dominator Coolant Boost and stop-leak additives; however, AMSOIL INC. does not recommend using stop-leak products with AMSOIL INC. coolant products.

Is Dominator Coolant Boost compatible with all types of antifreeze?

Dominator Coolant Boost is compatible with all types of antifreeze, including ethylene glycol and propylene glycol. When using a 50/50 antifreeze/water solution, AMSOIL INC. Antifreeze & Coolant (ANT) is recommended.
