AMSOIL’s Newest Product Decreases Operating Temperatures Even Further

Racers demand lower engine operating temperatures in order to achieve maximum efficiency and horsepower on the track, while the straight water coolant used by many racers opens engines up to damaging radiator and water pump corrosion. AMSOIL Dominator® Coolant Boost (RDCB) provides racers and motorists with significantly lower engine operating temperatures, quicker engine warm-up times and advanced corrosion protection.

Dominator Coolant Boost is formulated with proprietary tiered surfactant technology, providing quick and effective heat transfer inside radiators and cylinder heads, which results in reduced operating temperatures, more efficient operation, increased horsepower and significantly reduced engine warm-up times in cold weather. Coolant Boost 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.

The proof is in the pudding. Tests results tell it all.   Check out all the AMSOIL products at www.amsoil.com and use ZO 9792 when making inquiries to AMSOIL.

Temperature Reduction Dynamometer Test
To test the temperature reduction capabilities of Dominator Coolant Boost, dyno tests were performed on a Chevy 350 cubic inch engine with an aluminum block and cylinder heads. Running the test with both straight water and water treated with Coolant Boost, the engine was operated at 4,500 rpm until coolant temperature stabilized.

COOLANT MIXTURE STABILIZED COOLANT TEMPERATURE
Straight Water
221°F
Water with Coolant Boost
202°F

Test results show water treated with Coolant Boost provided a 19°F temperature reduction.

Aluminum Corrosion Test
The Aluminum Corrosion Test (ASTM D-4340) measures the corrosion protection properties of Dominator Coolant Boost in modern automobile and high-performance race engines with aluminum cylinder heads. A cast aluminum puck was heated to 275°F at 28 PSI and exposed to the test coolant mixture for one week. Weight loss of less than 1.0 mg is required to pass the test.

COOLANT MIXTURE WEIGHT LOSS
Straight Water 3.97 mg/cm2/wk
Water with Coolant Boost 0.14 mg/cm2/wk

Test results show water treated with Coolant Boost easily passed the Aluminum Corrosion Test.

Metal Corrosion Test
The Metal Corrosion Test (ASTM D-2570) measures corrosion protection properties in automotive cooling systems. Using ASTM corrosive water designed to simulate hard and corrosive water in degraded coolant, six metal coupons constructed of the most common metals in automotive cooling systems were exposed to the test coolant mixture at 190°F. The coolant was maintained at a temperature and flow rate equivalent to the operating conditions seen in most passenger vehicles. Corrosive weight loss suffered during the test determines the additive’s corrosion protection properties.

METAL STRAIGHT WATER
WEIGHT LOSS
WATER WITH COOLANT BOOST
WEIGHT LOSS
Copper 66mg 7mg
Solder 120mg 0mg
Brass 59mg 3mg
Steel 54mg 0mg
Cast Iron 117mg 0mg
Cast Aluminum 89mg 0mg

Test results show water treated with Coolant Boost significantly reduced weight loss due to corrosion.

Recommendations
Dominator Coolant Boost is recommended with both racing applications using straight water coolant and automotive applications using 50/50 coolant/water mixtures.

Directions: With engine off and cool, make sure cooling system is filled with selected coolant. Shake bottle and pour calculated amount of Coolant Boost into radiator. Start engine, turn heat on high and run for 15 minutes. Do NOT use distilled water unless mixed with 50% antifreeze.

Dosage: For straight water applications, add 2 fl. oz. of Coolant Boost per quart of tap or softened water. For 50/50 coolant/water applications, add 1 fl . oz. of Coolant Boost per quart of 50/50 mix.

Frequency: In applications using Coolant Boost with straight water, drain and re-fill the coolant system and add Coolant Boost once per year or when indicated by color change. A distinctive pH color change indicates when the pH has fallen to a point where corrosion can set in. When the Coolant Boost/water mixture changes from pink to clear, another dosage of Coolant Boost should be added. Monitoring the pH level will ensure all vital areas of the cooling system are protected against corrosion.

In applications using Coolant Boost with 50/50 coolant/water mixtures, add Coolant Boost once per year or every 30,000 miles, whichever comes first. Follow coolant manufacturer recommendations for coolant change intervals.

API Comparative Motor Oil Testing

Overview

AMSOIL Synthetic 10W-30 Motor Oil (ATM) and 10 competing conventional, synthetic and synthetic blend 10W-30 motor oils were subjected to a series of motor oil tests. The competing oils included petroleum-based Castrol GTX, Chevron Supreme, Shell Formula, Valvoline SynPower, Mobil1 Extended Performance, Motorcraft Synthetic Blend, Kendall GT-1 High Performance, Pennzoil Platinum, Quaker State Horse Power and Trop Artic Synthetic Blend.

AMSOIL Extends Oil Life

Thin Film Oxygen Uptake Test – ASTM D-4742

The Thin Film Oxygen Uptake Test (TFOUT) is used to evaluate engine oil’s ability to resist heat and oxygen breakdown when contaminated with oxidized/nitrated fuel, water, and soluble metals such as lead, copper, iron, manganese and silicon. This test is designed to mimic the operating conditions of a gasoline engine.

AMSOIL 10W-30 Synthetic Motor Oil has superior heat and oxidation resistance to control sludge deposits and extend oil life. Engines stay clean for maximum protection and oil changes are reduced, saving time and money.

Maximizes Fuel Economy, Reduces Oil Consumption and Emissions

NOACK Volatility Test – ASTM D-5800

The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions.

AMSOIL 10W-30 Synthetic Motor Oil resists high temperature volatilization (evaporation) better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.

Improves Cold Temperature Startup

Pour Point – ASTM D-97

The Pour Point Test determines the lowest temperature at which a lubricant will flow. The lower a lubricant’s pour point, the better protection it provides in low temperature service. Unlike conventional oils that solidify in cold temperatures, AMSOIL 10W-30 Synthetic Motor oil remains fluid down to -58° F. AMSOIL Synthetic Motor Oil helps engines turn over easier and flows quickly to engine parts for critical start-up protection. Engines start faster and wear is greatly reduced for extended engine life.

Controls Acid Formation

Total Base Number – ASTM D-2896

Total Base Number (TBN) is the measurement of a lubricant’s reserve alkalinity, which aids in the control of acids formed during the combustion process. The higher a motor oil’s TBN, the more effective it is in suspending wear-causing contaminants and reducing the corrosive effects of acids over an extended period of time.

The high TBN of AMSOIL Synthetic 10W-30 Motor Oil allows it to effectively combat wear-causing contaminants and acids, providing superior protection and performance over extended drain intervals.

Helps Engines Start Easier

Cold Cranking Viscosity – ASTM D-5293

The Cold Crank Simulator Test determines the apparent viscosity of lubricants at low temperatures and high shear rates. Viscosity of lubricants under these conditions is directly related to engine cranking and startability. The lower a lubricant’s cold crank viscosity, the easier an engine will turn over in cold temperatures. The low cold crank viscosity of AMSOIL Synthetic 10W-30 Motor Oil reduces drag on moving engine parts and allows engines to achieve critical cranking speed in extremely frigid temperatures. Engines turn over quickly and dependably in the coldest winter temperatures.

Protects Against Wear

Four-Ball Wear – ASTM D-4172

The Four-Ball Wear Test evaluates the protection provided by engine oil under conditions of pressure and sliding motion. The size of the scar left as a result of the test determines the amount of wear protection the lubricant provides. The smaller the wear scar, the better the protection. Tests show that AMSOIL 10W-30 Synthetic Motor Oil has better antiwear performance than all other oils tested. With AMSOIL Synthetic Motor Oil, engine life can be extended and major repairs are often reduced.

Saves Money

Cost Per 25,000 Miles

By extending oil drain intervals through its premium formulation, AMSOIL Synthetic Motor Oil saves drivers money. A value comparison shows AMSOIL Synthetic Motor Oil costs less than competing motor oils over 25,000 miles.

While competing motor oils must be changed up to five times over 25,000 miles, AMSOIL Synthetic Motor Oil is only changed once, saving both time and money.
