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-20 (ASM): API SN (Resource Conserving),
SM…; ILSAC GF-5, GF-4…; ACEA A5/B5, A1/B1; GM 6094M; Ford
WSS-M2C945-A, WSS-M2C930-A; Chrysler MS-6395N
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.
