Motor Oil Test and Comparison
AMSOIL
Synthetic 10W-30 Motor Oil (ATM) and 10 competing conventional
and synthetic 10W-30 motor oils were subjected to a series
of ASTM motor oil tests. The competing oils included petroleum-based
Castro GTX Drive Hard, Mobil Drive Clean, Pennzoil with Purebase,
Quaker State Peak Performance and Valvoline, as well as synthetic-based
Valvoline Synpower, Quaker State, Castrol Syntec, Pennzoil
and Mobil SuperSyn Multi-Vehicle.
Seven 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 oils in high temperature service. Pour
Point indicates the lowest temperature at which a fluid will
flow. Total 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.
Thin-Film Oxygen Uptake (ASTMD-4742)
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 oil is recorded. As shown in the graph,
AMSOIL
Synthetic 10W-30 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 its superior wear protection
and lubricating properties and maximizing fuel efficiency.
High Temperature/High Shear (ASTM
D-4683)
The High
Temperature/High Shear Test measures a lubricant's viscosity
under severe hightemperature and shear conditions that resemble
highly-loaded journal bearings in fired internal combustion
engines. In order to prevent bearing wear, it is important for
a lubricant to maintain its protective viscosity under severe
operating conditions. The minimum High Temperature/High Shear
viscosity for a 30 weight oil is 2.9 cP. As shown in the graph,
AMSOIL
Synthetic 10W-30 Motor Oil surpasses this minimum standard
and displayed the highest High Temperature/High Shear viscosity
in the group.
The superior viscosity retention
of AMSOIL
Synthetic 10W-30 Motor Oil in the face of severe temperature
and shear conditions allows it to provide continuous, unsurpassed
protection for engine bearings, extending equipment life and
preventing wear.
NOACK Volatility (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. A maximum of 15 percent evaporation loss is allowable
to meet API SL and ILSAC GF-3 specifications. As shown in the
graph, AMSOIL
10W-30 Synthetic Motor Oil outperformed its nearest competitor
by over 30 percent.
The extremely low volatility
of AMSOIL
Synthetic 10W-30 Motor Oil allows it to maintain its superior
protective and performance qualities throughout extended drain
intervals, even when faced with severe operating temperatures.
In addition, oil consumption and emissions are minimized and
fuel efficiency is maximized.
Pour Point (ASTM D-97)
The Pour
Point Test determines the lowest temperature at which a
lubricant will flow when cooled under prescribed conditions.
The lower a lubricant's pour point, the better protection it
provides in low temperature service. As shown in the graph,
AMSOIL Synthetic 10W-30 Motor Oil has the lowest pour point
of the tested oils.
The low pour point of AMSOIL
10W-30 Synthetic Motor Oil allows it to maintain its fluidity
in extremely low temperatures, reducing drag on moving vehicle
parts, providing critical engine components with quick, essential
lubrication and easing startup in cold temperatures. Wear
is greatly reduced and equipment life is extended.
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. As shown in the graph, AMSOIL Synthetic 10W-30 Motor
Oil has the highest TBN of the tested oils.
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.
Cold Crank Simulator (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. 10W motor oils are tested at -25 degrees C and
must have a viscosity below 7000 cP to pass. As shown in the
graph, AMSOIL Synthetic 10W-30 Motor Oil is well below the maximum
requirement, while many of the competing oils barely pass.
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.
Four Ball Wear (ASTM D-4172)
The Four
Ball Wear Test determines the wear protection properties
of a lubricant. Three metal balls are clamped together and covered
with the test lubricant, while a rotating fourth ball is pressed
against them in sliding contact. This contact typically produces
a wear scar, which is measured and recorded. The smaller the
average wear scar, the better the wear protection provided by
the lubricant. As shown in the graph, AMSOIL
Synthetic 10W-30 Motor Oil produced the smallest wear scar
of the tested lubricants.
AMSOIL
Synthetic 10W-30 Motor Oil provides unsurpassed protection
against engine wear. Equipment life is extended, and repairs,
downtime and expenses are reduced.
AMSOIL INC. has been the leader
in synthetic motor oil formulation since its introduction
of the world's first API rated synthetic motor oil in 1972.
By specializing exclusively in the synthetic lubricant technology,
AMSOIL is able to optimize the most advanced chemistries available.
The "Genuine Synthetic PAO Formulated" designation
displayed on AMSOIL packaging indicates that the oils are
formulated with Polyalphaolefin (PAO) synthetic base stocks.
This chemistry is the industry's premier base stock technology.
Unlike conventional mineral-based chemistries, AMSOIL PAO
base stocks contain fully saturated, hydrogenated molecules
and are free of wax and other impurities. Combined with an
exact balance of premium additives, itdelivers superior hot
and cold temperature performance, resists oxidation and acid
formation and provides long-term wear protection.
AMSOIL "General
Synthetic PAO Formulated" oils have shattered the parameters
of the most rigorous industry testing and set the standard
for all other motor oils.

Why Motor Oil Deteriorates
It is common knowledge
that, at some point, engine oil must be changed. It's something
that is preached relentlessly to vehicle owners by vehicle
manufacturers, quick lubes and oil companies. But consumers
are widely unaware of what exactly makes oil changes necessary.
Many factors contribute
to a motor oil's demise, but it is essentially the accumulation
of contaminants in the oil and chemical changes in the oil
itself that make a motor unfit for further service. With time,
it is inevitable that the oil will be contaminated by dirt
or sludge, or succumb to the extreme pressures or temperatures
found inside an engine. AMSOIL Motor Oils are formulated with
the industry's most advanced synthetic base stocks and additive
packages to combat the forces that deteriorate conventional
oils. (read

What is the NOACK Volatility
Test?
Volatization is a term used to describe
what happens to a fluid as it is heated to the point it begins
to "boil off." Upon reaching a certain temperature,
oil will begin to lose some of its lighter weight molecules
as they "boil off" and leave heavier weight molecules
behind. Not only does this cause higher oil consumption, this
process can also cause increased viscosity making the oil
more difficult to circulate through the lubrication system.

Another
AMSOIL First
More than 20 years
ago, AMSOIL began using the NOACK volatility test as a comparison
tool and measurement of quality. Back then, nearly every oil
tested side-by-side with AMSOIL synthetic motor oils failed,
and those that passed barely squeaked by. Other oil companies
paid no attention to NOACK results until Ford Motor Company
made it a requirement for service fill oils, validating what
AMSOIL had said all along.
THE
NOACK Volatility Test
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
Synthetic Motor Oil resists high temperature volatization
better than other motor oils. AMSOIL Synthetic Motor
Oil maintains peak fuel efficiency and reduces oil consumption
and emissions. |
