Overview
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
conventional Castrol
GTX, Chevron
Supreme, and Formula
Shell,
synthetic-blends
Kendall GT-1 HP,
Trop Artic and
Motorcraft, and
full-synthetic
Pennzoil Platinum,
Valvoline Synpower,
Quaker State Horse

AMSOIL
Extends Oil Life
Thin Film Oxygen
Uptake Test -
ASTM D-4742
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.
Maximizes
Fuel Economy,
Reduces Oil
Consumption and
Emissions
NOACK Volatility
Test - 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.
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
Pour Point -
ASTM D-97
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 - 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.
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
Cold Cranking
Viscosity - 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.
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
Four-Ball Wear -
ASTM D-4172
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.
