AMSOIL Signature Series 100% Synthetic 10W-30 Motor Oil
Product Code: ATM
AMSOIL Signature Series Synthetic Motor Oil delivers extraordinary
lubrication in all types of automotive petrol 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
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
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.
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
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.
AMSOIL Signature Series Synthetic Motor Oil is excellent for
use in all types of petrol-fueled vehicles. It is recommended
for all domestic and foreign vehicles requiring any of the listed
10W-30 (ATM): API SN (Resource Conserving), SM…; ILSAC GF-5,
GF-4…; ACEA A5/B5, A1/B1; GM LL-A-025, 6094M, 4718M;
Ford WSS-M2C205-A; Chrysler MS-6395
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.
AMSOIL Signature Series Synthetic Motor Oil is recommended
for extended drain intervals in unmodified(1), mechanically
sound(2) petrol-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-petrol-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
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.
