Provides Effective Heat Transfer and Enhanced Corrosion ProtectionRacers demand lower engine operating temperatures in order to achieve maximum ef ciency and horsepower on the track. Many racers use straight water as a coolant, which invites damaging radiator and water-pump corrosion. AMSOIL DOMINATOR® Coolant Boost (RDCB) provides racers and motorists with signi cantly lower engine operating temperatures, quicker warm-up times and advanced corrosion protection.

Temperature Reduction Dynamometer Test
To test temperature-reduction capabilities, controlled engine dynamometer (dyno) tests were performed on a 350 cubic inch Chevy* engine with an aluminum block and cylinder heads. In each phase of testing, the engine was operated at 4,500 rpm until coolant temperature stabilized. As benchmarks for the test, straight water stabilized at 220°F and a 50/50 antifreeze/water mixture stabilized at 228°F.
