vs. the Competition
An independent laboratory using American Society for Testing
and Materials Standards(ASTM) tests subjected AMSOIL Synthetic 10W-30 Motor Oil (ATM) along with 10 competing
conventional and synthetic10W- 30 motor oils to a series of motor oil tests.
The competing oils included petroleum based Castrol GTX, Chevron Supreme, Halvoline, Formula Shell and Penzoil, as well as
synthetic blends Trop Artic and Motorcraft, and
full-synthetic Penzoil Platinum, Quaker State Advanced Full Synthetic and Mobil 1
impressive test results show AMSOIL Synthetic
10W-30 Motor Oil outperformed the
competitors in each test.
Seven tests were run on the motor oils.
The Thin-Film Oxygen Uptake Test (TFOUT) measures the oxidation stability
of engine oils.
EXTENDS OIL LIFE & PROTECTS HOT
ENGINES...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
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
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
Pour Point indicates the lowest temperature at which a fluid will
IMPROVES COLD TEMPERATURE
STARTS...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.
Total Base Number (TBN) is the measurement of a lubricant's reserve
alkalinity for combating acids.
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.
The Cold Cranking Simulator Test (CCS) measures a lubricant's viscosity
at low temperatures and high shear rates.
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.
The Four-Ball Wear Test measures a lubricant's wear protection
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.
