The chart on the right shows the average
temperatures of Gearboxes A and B
from 1 1/2 hours to 3 1/2 hours of the
demonstration (the period when gearbox
temperatures were leveling-off or
stable). AMSOIL Gear Lube reduces
bearing, fluid and motor temperatures as
much as 34 degrees F in comparison to
its conventional counterpart. Cooler
operation means less friction, better
energy savings and reduced maintenance.

DIN 51581: The Noack
Volatility Test

How important is heat reduction to an engine? The cooling
system of a diesel engine under full load removes enough
heat every hour to transform the engine to a molten state.
About 8-9,000 gallons of water are pumped through the
cooling system of an average diesel in one hour. During one
day, enough water is pumped to fill a large swimming pool.

Now consider that less than 60% of this heat is dissipated
by the cooling system. The rest is left to the engine and it's
oil.

Volatility is a measure of how the oil stands up to heat. If
an oil can't take the heat, it boils off or volatilizes. When it
does this, the remaining oil becomes thicker and forms
lacquer and damaging deposits on precision engine parts.
While a typical petroleum oil will excessively break down at
250 degrees F, AMSOIL Oils have flash points of up to
460 degrees F and fire points of up to 493 degrees F.

The chart on the right shows test results of five oils that
underwent the Noack Volatility Test. In Europe, the
CCMC (their main automotive regulative committee) fails
any oil that has a volatility, or weight loss, of 13% or more.
Knowing this, what oil would you want protecting your
engine?

Reduce Emissions and Waste Oil for a Cleaner Environment

As you can see from the volatility graph above, almost 25%
of some oils boil off inot the air. That means one-quarter of
the oil you pour into your crankcase can exit through the
exhaust system. AMSOIL substantially reduces oil
consumption and emissions.

But what's most remarkable is AMSOIL Lubricants last
vastly longer than conventional oils. Heavy trucks and
passenger cars alike have used 100,000 mile drain intervals
with AMSOIL (using oil analysis at regular drain intervals).
That's a savings of hundreds of quarts of oil, which means
less material costs and greatly reduced disposal of waste
oil. AMSOIL saves your money and the environment!

AMSOIL Synthetic 10W-30 Motor
Oil (ATM) and 10 competing
conventional and synthetic 10W-30
motor oils were subjected to a
series of API motor oil tests. The
competing oils included
petroleum-based Castrol GTX
Drive Hared, Mobile Drive Clean,
Pennzoil with Purebase, Quaker
State Peak Performance and
Valvoline, as well as
synthetic-based Valvoline
Synpower, Quaker State, Castrol
Syntec, Pennzoil and Mobile 1
SuperSyn Multi-Vehicle

Seven API Tests were run on the motor oils. The Thin-Film Oxygen Uptake Test (TFOUT) measures the
oxidation stability of engine oils. The high Temperature/High Shear Test (HTHS) measures a lubricant's
viscosity under severe Operating conditions. The NOACK Volatility Test measures the evaporation loss of
Base Number (TBN) is the measurement of a lubricant's reserve alkalinity for combating acids. The Cold
Cranking Simulator Test (CCS) measures a lubricant's viscosity at low temperatures and high shear rates.
The Four-Ball Wear Test measures a lubricant's wear protection properties. The impressive test results
show AMSOIL Synthetic 10W-30 Motor Oil outperformed the competitors in each test.

The Thin-Film Oxygen Uptake Test evaluates the oxidation
stability of lubricating oils. A mixture of the test oil and
chemistries found in gasoline engine operation
(oxidized/nitrated fuel, soluble metals and distilled water) are
placed in a test vessel, which is pressurized with oxygen and
placed in a heated bath. Anti-oxidant breakdown is evident
when the oxygen pressure in the vessel rapidly decreases. At
this point, the induction time (break point) of the oils is
recorded. As shown in this graph, AMSOIL Synthetic 10W-40
Motor Oil had the highest induction time of all the tested oils. In
fact, it didn't reach its break point in over 500 minutes of
testing.

The superior oxidation stability of AMSOIL Synthetic 10W-30
Motor Oil allows it to effectively resist the formation of engine
deposits and sludge, keeping engines running clean and
efficient and extending oil life. It also resists thickening,
maintaining it's superior wear protection and lubricating
properties and maximizing fuel efficiency.
