Praises AMSOIL!

Publishing Company, Inc.
In the March 2003 issue of
Lubes 'n' Greases,
Automotive Editor David McFall wrote an
in-depth article on the subject of extended oil drain intervals and
touted AMSOIL as a safe, cost-effective and environmentally preferred
choice. He praised AMSOIL for their commitment to excellence and labeled
AMSOIL "unshackled"
for never conforming to industry norms and standards.
Compare AMSOIL to Mobil 1,
Pennzoil, Quaker State, Castrol and more!
AMSOIL 10W-30 Motor Oil and ten
competing oils were subjected to a series of tests. AMSOIL
outperformed all the competitors in nearly every test! See the
impressive test results!

Comparative Motor Oil Testing

|
 |
 |
|
AMSOIL Synthetic 10W-30 Motor Oil
(ATM) and ten competing conventional, synthetic blend and full synthetic 10W-30 motor oils were subjected
to a series of American Petroleum Institute (API) motor oil tests. The competing
oils included the following oils: |
Petroleum Oils:
- Castrol GTX
- Chevron Supreme
- Havoline
- Formula Shell
- Pennzoil
|
Synthetic Blends:
|
Synthetic Oils:
- AMSOIL (ATM)
- Pennzoil Platinum
- Quaker State Advanced Full Synthetic
- Mobil 1 Extended Performance
|
These seven API tests were run on the motor oils:
|
|
|
The following test results demonstrate that
AMSOIL Synthetic 10W-30 Motor Oil outperforms Pennzoil,
Valvoline, Castrol, Quaker State, and even Mobil One: |
Significance
|
|
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. |
What It Means
|
|
Lubricants with high induction times are preferred.
- Resists the formation of engine deposits and sludge, keeping engines
running clean and efficient
- Resists thickening, for superior wear protection and maximum fuel
efficiency
- Longer oil life
|
Results
|
|
AMSOIL Synthetic 10W-30 Motor Oil had the highest induction time of all the
tested oils. In fact, it didn't even reach its break point in over 500 minutes of
testing!
AMSOIL was still going strong, while Mobil 1 and
all the other oils tested broke down before the test was terminated!

ASTM D-4742 |
 
High Temperature/High
Shear
|
Significance
|
|
Measures viscosity and the rate of temporary and
permanent viscosity loss of an oil under conditions of high temperature and high
shear rates. (The temperature and shear rate of this test is considered
representative of the conditions encountered in the bearings of car engines in
severe service.)
|
What It Means
|
|
Lubricants with high scores are preferred.
- Maintains their viscosity in the face of high temperature and shear
conditions
- Prevents bearing wear
|
Results
|
|
AMSOIL Synthetic 10W-30 Motor Oil does not "shear back" and thin out like other
motor oils. AMSOIL surpasses the minimum
standard of 2.9 CP (for a 30 weight oil) and displayed the highest viscosity in
the group, proving that AMSOIL provides the best protection for engine bearings.

ASTM D-4683 |
Significance
|
|
The NOACK Volatility Test is a standard test used
to measure the evaporation loss of lubricating oils in high temperature service. It provides a basis
for estimating the approximate useful life of a lubricant. In the NOACK, a
test specimen of oil is heated to 482°F and held at
that temperature for one hour. The pre-test weight of the specimen is
compared to the post-test weight, and the test oil’s percentage of weight loss
is determined.
The NOACK Volatility Test was developed in Germany and has long been a
specification test for European motor oils. Volatility
testing became a requirement for North American motor oils in 1992, with the
introduction of API SH/ILSAC GF-1 oils. Volatility standards were
tightened with the 1996 introduction of API SJ/ILSAC GF-2 oils, which required a
weight loss limit of 22%. A maximum of 15% evaporation loss is allowable to meet
the current API SM/ILSAC GF-4 specifications.
|
What It Means
|
|
Lubricants with low NOACK scores are
preferred. Low NOACK scores indicate an oil that is less prone to
evaporation at high operating temperatures. Low NOACK scores indicates an
oil that will keep their original protective and performance qualities longer.
- Better oil circulation
- Maximum fuel efficiency
- Reduced oil consumption
- Less deposit formation
- Stable viscosity for low and high temperature wear protection
- Fewer emissions
- Longer oil life
|
Results
|
|
AMSOIL Synthetic 10W-30 Motor Oil had the lowest NOACK test score, meaning
it resists high temperature volatilization (evaporation) better than other
motor oils. |
|
|
|
ASTM D-5800 |
|
Note: In the early 1980s, AMSOIL became the first
motor oil manufacturer in the United States to routinely subject its oils to NOACK
testing and report the results. At a time when U.S. oils were not even required to meet any volatility standards, AMSOIL was formulating oils to beat
stringent European standards. Now, the future of the motor oil market is being
shaped by oil volatility limits.
|
Significance
|
|
Determines the lowest temperature at which the oil flows.
|
What It Means
|
|
The lower the pour point, the more useful the
lubricant is in cold temperatures.
- Easier and more dependable cold weather starts
- Wear/friction reduction
- Extends equipment life
|
Results
|
|
The low pour point of AMSOIL Synthetic 10W-30 Motor Oil allows it to maintain
its fluidity in extremely low temperatures.
|
|
|
|
ASTM D-97 |
Significance
|
|
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.
Most passenger car motor oils offer only 7
TBN and are formulated with detergents that quickly lose TBN value. With
TBN loss, oils lose their ability to neutralize acids, prevent high temperature
deposits and inhibit rust.
TBN loss is a primary reason oils require
changing.
|
What It Means
|
|
The higher a motor oil's TBN, the more effective it is.
- Suspends wear-causing contaminants
- Reduces the corrosive effects of acids
- Longer oil life
|
Results
|
|
AMSOIL Synthetic 10W-30 Motor Oil contains a highly effective
detergent-alkalinity additive, which gives it a higher TBN than other motor
oils, which gives it a longer oil life than other motor oils.
|
|
|
|
ASTM D-2896 |
Significance
|
|
Determines the apparent viscosity of motor oils between -40°F and 32°F and at
high shear rates. (The temperature and shear rate of this test is considered
representative of the conditions encountered by car engines cranking in cold
temperatures.) The results are used to assign SAE "W" grades.
|
What It Means
|
|
Low values indicate
improved cold temperature pumpability and flowability. (Oils that thicken too
much in cold temperatures won’t allow engines to turn fast enough to start.)
- Easier and more dependable cold weather starts
- Wear/friction reduction
- Longer oil life
- Improved fuel economy
|
Results
|
|
AMSOIL Synthetic 10W-30 Motor Oil is well below the maximum viscosity
requirement of 7000 cP (many of the competing oils barely pass), which allows
engines to turn over quickly and dependably in the coldest winter temperatures.
|
|
|
|
ASTM D-5293 |
Significance
|
|
Evaluates the friction- and wear-control ability of a lubricant. The Four
Ball Wear Test puts one rotating ½-inch diameter steel ball against three
fixed ½-inch diameter steel balls, which are covered with the test
lubricant, under specific conditions of pressure, temperature, revolutions
per minute and duration. Wear scars are measured and averaged.
|
What It Means
|
|
The smaller the wear scar, the better the protection provided by the lubricant.
- Longer equipment life
- Fewer repairs
- Reduced downtime and maintenance expenses
- Longer oil life
|
Results
|
|
AMSOIL Synthetic 10W-30 Motor Oil produced the smallest wear
scar of the tested lubricants, providing unsurpassed protection against
engine wear, up to 4 times better!
|
|
|
|
ASTM D-4172 |
| AMSOIL, the leader in automotive synthetic
lubrication, produced the world’s first API-qualified synthetic
