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.

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.
