Comparative Motor Oil Testing
API Motor Oil Testing:
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 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
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 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 (ASTM D-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 high temperature 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
Synthetic 10W-30 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 Synthetic 10W-30 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°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 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, it delivers superior hot and cold
temperature performance, resists oxidation and acid formation and
provides long-term wear protection. AMSOIL “Genuine Synthetic PAO
Formulated” oils have shattered the parameters of the most rigorous
industry testing and set the standard for all other motor oils.
AMSOIL
is the undisputed leader in synthetics.............

Since 1972, AMSOIL Synthetics have proven to be the
BEST. AMSOIL also engineers and manufactures Super Duty Oil filters which have a
12,500 mile service life as well as specialized filtration systems for
commercial and fleet applications in cars and light, medium and heavy trucks
which can filter particles down to less than one micron ( a standard full flow
oil filter can only filter to 20-25 microns with any degree of efficiency) making oil changes virtually unnecessary and virtually eliminating engine wear.
These filters have been proven by millions of miles of over-the road trucks,
construction equipment and fleet service.
