AMSOIL, the leader in automotive synthetic lubrication, produced the worlds first
API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL,
the First in Synthetics®, to do the best job protecting your engine.
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
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:
0W-20 (ASM): API SN (Resource Conserving), SM…; ILSAC GF-5, GF-4…;
ACEA A1/B1; GM dexos1™ (supersedes 6094M) Fortified with detergents that exceed
dexos1 sulfated ash specifications; Chrysler MS-6395; Ford WSS-M2C947-A

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.
Aftermarket oil additives are not recommended for use with
AMSOIL synthetic motor oils.
- Normal Service – Up to 25,000 miles, 700 hours of operation or one year, whichever comes first, in personal vehicles not operating under Severe Service.
- Severe Service – Up to 15,000 miles, 700 hours of operation or one year, whichever comes first.
Severe Service: Primarily short trips (less than 10 miles [16
km]); turbo/supercharged engines; commercial or fleet vehicles;
excessive idling; first-time use of AMSOIL motor oil in a vehicle
with more than 100,000 miles; frequent towing, hauling, plowing
or driving in dusty conditions.
- Modified engines (non-stock) and those using E85 fuel are
excluded from extended drain recommendations.
- Change at the vehicle manufacturer’s recommended drain
interval outside U.S. and Canada.
- AMSOIL Ea® Full-Flow Oil Filters are designed for extended
change intervals. With other brands, do not exceed six months
or 10,000 miles unless longer intervals are recommended by
the vehicle manufacturer.
- Check oil regularly to maintain proper fill levels.
AMSOIL Ea® Full-Flow Oil Filters are designed for extended
change intervals. They stop smaller particles, flow more oil and
last longer than regular filters. For best performance, use
AMSOIL Ea Full-Flow Oil Filters.
