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, Havoline, Formula Shell and
Pennzoil, as well as synthetic-blends Trop Artic and
Motorcraft, and
full-synthetic Pennzoil Platinum, Quaker State Advanced Full Synthetic and
Mobil 1 Extended Performance. 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) indicates the degree to which a lubricant can impact cold weather
starting. The impressive test results show AMSOIL Synthetic 10W-30 Motor
Oil outperformed the competitors in nearly every test.
EXTENDS
OIL LIFE
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.

PROTECTS
HOT ENGINES
The High Temperature/High Shear Test
measures a lubricant’s viscosity under severe high temperature and shear
conditions that are similar to severe service applications in an engine.
In order to prevent wear, it is important for a lubricant to maintain its
protective viscosity level under severe operating conditions. AMSOIL
10W-30 Synthetic Motor Oil does not “shear back” and thin out like
other motor oils. Its superior viscosity stability provides unsurpassed
bearing protection for dependable engine operation, especially during hot
operating conditions.

MAXIMIZES
FUEL ECONOMY, REDUCES OIL CONSUMPTION AND EMISSIONS
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
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 (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
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
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.
