AMSOIL Signature Series Synthetic Motor Oil delivers
extraordinary lubrication in all types of automotive
gasoline engines. By combining industry-premier synthetic
technology with AMSOIL premium additives, Signature Series
Synthetic Motor Oil exceeds the higher performance demands
of modern engines. It withstands the stress of higher
horsepower, higher heat and complicated emissions control
systems. Signature Series Synthetic Motor Oil is
engineered to outperform competitive conventional and
synthetic motor oils. It delivers long-lasting performance
and protection.
AMSOIL, the leader in automotive
synthetic lubrication, produced the world’s 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.
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 Synthetic Motor Oil is designed to
deliver the best possible engine protection, cleanliness
and performance over extended drain intervals. It reduces
vehicle maintenance and waste oil disposal costs.
Maximizes Fuel Economy
AMSOIL Signature Series Synthetic Motor Oil is designed to
maximize energy efficiency for improved 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.
Reduces Engine Wear
Signature Series Synthetic Motor Oil provides outstanding
anti-wear protection. It has excellent viscosity film
strength to separate metal surfaces and robust anti-wear
additives to further reduce wear in metal-to-metal contact
regions for improved engine life.
Reduces Oil Consumption and Emissions
Volatility (burn-off) occurs when oil gets hot, causing
high oil consumption and emissions. AMSOIL Signature
Series Synthetic Motor Oil exhibits an extremely low
volatility rate; it controls volatility-related oil
consumption and emissions.
Excels in Extreme Temperatures
AMSOIL Signature Series Synthetic Motor Oil resists
thermal (heat) breakdown better than conventional oils. It
is heavily fortified with detergent and dispersant
additives to help prevent sludge deposits and keep engines
clean. And unlike conventional oils, Signature Series
Synthetic Motor Oil contains no wax, staying fluid in the
coldest winter temperatures for easier starting, improved
oil flow and reduced bearing wear.
APPLICATIONS
AMSOIL Signature Series Synthetic Motor Oil is excellent
for use in all types of gasoline-fueled vehicles. It is
recommended for all domestic and foreign vehicles
requiring any of the listed performance specifications:
0W-30 (AZO): API SN (Resource
Conserving), SM…; ILSAC GF-5, GF-4…; ACEA A5/B5, A1/B1;
Ford WSS-M2C946-A, WSS-M2C929-A; Chrysler MS-6395N;
Suitable as a replacement for GM dexos1™ (supersedes
LL-A-025, 6094M and 4718M)
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 the 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.
SERVICE LIFE
AMSOIL Signature Series Synthetic Motor Oil is recommended
for extended drain intervals in unmodified(1),
mechanically sound(2) gasoline-fueled vehicles as follows:
• Normal Service(3) – Up to 25,000 miles or one year,
whichever comes first.
• Severe Service(4) – Up to 15,000 miles or one year,
whichever comes first.
• In all non-gasoline-fueled vehicle applications, extend
the oil change interval according to oil analysis or
follow the OEM* drain interval.
*OEM – Original Equipment Manufacturer
(1) Engines operating under modified conditions
(non-stock) are excluded from extended drain
recommendations. Examples include the use of performance
computer chips; non-OEM approved exhaust, fuel or air
induction systems; and the use of fuels other than those
recommended for normal operation by the manufacturer.
(2) Mechanically sound engines are in good working
condition and do not, for example, leak or consume
excessive amounts of oil, are not worn out, do not
overheat, do not leak antifreeze and have properly working
emissions control systems. AMSOIL recommends repairing
malfunctioning engines prior to the installation of AMSOIL
synthetic oils.
(3) Personal vehicles frequently traveling greater than
10 miles (16 km) at a time and not operating under severe
service.
(4) Turbo/supercharged engines, commercial or fleet
vehicles, excessive idling, vehicles with more than
100,000 miles without prior continuous use of AMSOIL motor
oil, daily short-trip driving less than 10 miles (16 km),
frequent towing, plowing, hauling or dusty condition
driving.
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.
