extensive experience of AMSOIL, the First in Synthetics®, to do the best
job protecting your engine.
Protects Against Engine Wear
AMSOIL Signature Series Synthetic Motor Oil develops a strong fluid
film that keeps metal surfaces separated while its robust anti-wear
additives further reduce wear in metal-to-metal contact regions for
maximum engine life. The Sequence IVA Engine Test, which must be passed
to meet the industry-standard API SN specification, simulates extended
periods of stop-and-go driving. For 100 hours, the test engine cycles
between 50 minutes of idling and 10 minutes of elevated rpm –
conditions that encourage engine wear. The camshaft is then measured
for wear in 84 locations and an average score is determined. We used
Signature Series 0W-20, the lightest viscosity in the line, to further
increase the severity of the test. AMSOIL Signature Series Synthetic
Motor Oil provided 75 percent more engine protection against horsepower loss and wear1 than required by the industry standard, extending the life of vital components like pistons and cams.
| After rigorous third-party testing, the cam lobes show little-to-no wear. |

| SEQUENCE IVA ENGINE TEST Lower number = less wear |

1Based on independent testing of AMSOIL Signatur e Series 0W-20, in ASTM D6891 as required by the API SN specification.
Protects Pistons from Low-Speed Pre-Ignition Original equipment manufacturers (OEMs) like GM* have addressed the issue by designing tests to determine a motor oil’s ability to prevent LSPI. Signature Series Synthetic Motor Oil achieved 100 percent protection against LSPI1 in the engine test required by the GM dexos1 Gen 2 specification - zero occurrences were recorded throughout five consecutive tests. | Protects Turbochargers We challenged Signature Series to the GM Turbo Coking Test, which consists of 2000 cycles of extreme heat soaks. An oil must limit the temperature change within the turbocharger to 13 percent or less to pass the test. Signature Series limited the temperature increase to only 3.6 percent, protecting the turbocharger 72 percent better than required2 by the GM dexos1® Gen 2 specification. |

Preserves Horsepower
The extreme durability of Signature Series Motor Oil ensures your
engine runs stronger, for longer. We installed Signature Series 5W-30
Synthetic Motor Oil in a Ford* F-150 with a new 3.5L Ecoboost engine to
test its ability to protect turbocharged direct-injection (TDGI)
engines from torque and horsepower loss during extended drain intervals
up to 25,000 miles. Power sweeps were done at the beginning and end of
the test to evaluate horsepower and torque retention. As the graph
shows, Signature Series helped maintain engine performance throughout
the 100,000 mile test.
Limits Oil Consumption
Signature Series has a uniform molecular structure that limits
evaporation and keeps it where it's needed most – protecting your
engine. Volatility (burn-off) occurs when oil gets hot, causing lighter
molecules to burn off or evaporate. This leads to oil thickening,
additive imbalance, higher emissions and oil consumption. The NOACK
Volatility test is the industry standard for evaluating motor oil high
temperature evaporation. It measures the percentage of burn-off after a
motor oil is placed under constant airflow at 482ºF for 1 hour. A lower
number indicates a better resistance to evaporation. Signature Series
falls far below the API limit for volatility, reducing the need for
frequent oil top-offs and limiting vehicle emissions.
Easier Cold-Starts
Signature Series Synthetic Motor Oil does not contain paraffins (wax)
and stays fluid in temperatures of -58ºF and lower. Extreme cold causes
other motor oils to thicken, starving vital moving parts of
lubrication, accelerating wear and even preventing vehicles from
starting. Signature Series provides 66 percent better cold-temperature performance for easier starting, better fuel economy, improved oil flow (as seen below) and reduced wear.
Maintains Protective Viscosity
We formulated Signature Series with superior thermal durability that
resists breakdown better than conventional and synthetic motor oils.
The Sequence IIIH Test uses the Chrysler 3.6L Pentastar engine to
evaluate a motor oil's ability to resist the damaging effects of heat.
The test is conducted with oil temperatures of 304ºF, 100ºF hotter than
normal operation, to accelerate oil thickening and deposits. Despite
the extreme conditions, Signature Series kept pistons clean and held
thickening to only 6 percent, a minimal amount compared to the proposed
specification limit of 150 percent.1 This stay-in-grade
performance helps maintain maximum power and fuel economy while also
ensuring advanced technologies like variable valve timing (VVT) operate
as designed throughout the entire drain interval.

Protects Your Engine
AMSOIL Signature Series Synthetic Motor Oil provides outstanding anti-wear protection. It
develops a strong fluid film that keeps metal surfaces separated while its robust anti-wear
additives further reduce wear in metal-to-metal contact regions for maximum engine life. In
the industry-standard Sequence IIIG Engine Test, AMSOIL Signature Series Synthetic Motor
Oil delivered 75 percent more engine protection against horsepower loss and wear than
required by a leading industry standard.** For details, see the Double-Length Sequence
IIIG Engine Test Technical Study (G3320).
Maximizes Fuel Economy
Signature Series Synthetic Motor Oil is designed to maximize energy efficiency for optimum
fuel economy. Unlike conventional oils, its uniform molecular structure helps it flow more
freely and reduce friction between metal surfaces. Anti-friction additives are included to
further improve energy efficiency.
Extends Drain Intervals
AMSOIL Signature Series Synthetic Motor Oil can extend drain intervals far beyond those
recommended for conventional oils. Its unique synthetic formulation and long-drain additive
system are inherently stable to resist oxidation and neutralize acids over longer periods.
Signature Series is designed to deliver outstanding engine protection, cleanliness and
performance over extended drain intervals. It reduces vehicle maintenance and waste oil.
Keeps Pistons Clean
Excess piston deposits can lead to pre-ignition and engine knocking, which results in lost
power, reduced fuel economy and, in severe cases, engine damage. Signature Series’
premium additives and naturally high resistance to extreme heat help keep pistons clean for
maximum engine performance. Signature Series prevents piston deposits 93 percent better
than required to meet the latest API standard.**
Excels in Extreme Temperatures
Signature Series resists thermal (heat) breakdown better than conventional and synthetic
motor oils. It is heavily fortified with detergent and dispersant additives to help prevent
sludge deposits and keep engines clean. Unlike conventional oils, Signature Series
contains no wax, staying fluid in sub-zero temperatures for easier starting, improved oil flow
and reduced wear.
Reduces Oil Consumption and Emissions
Volatility (burn-off) occurs when oil gets hot, causing high oil consumption and emissions.
Signature Series resists volatility better than other oils, helping reduce oil consumption and
emissions.
APPLICATIONS
AMSOIL Signature Series Synthetic Motor Oil is excellent for use
in all types of gasoline-fueled passenger cars and light trucks. It
is recommended for all domestic and foreign vehicles requiring
any of the following performance specifications:

COMPATIBILITY
AMSOIL Signature Series Synthetic Motor Oil is compatible
with other conventional and synthetic motor oils. Mixing AMSOIL
motor oils with other oils, however, will shorten the oil’s life expectancy
and reduce its performance benefits. AMSOIL does not
support extended drain intervals where oils have been mixed.
