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.
Any brand of oil filter may be used with Signature Series Synthetic Motor Oil. For maximum convenience, however, use an AMSOIL Ea® Oil Filter. Made of fully synthetic media with greater filtering efficiency and dirt-holding capacity than conventional filters, Ea Oil Filters are recommended for 25,000 miles/12 months or 15,000 miles/12 months, depending on application, which coincides with Signature Series' once-a-year drain interval. While Signature Series' 12-month service life remains intact if a non-Ea Oil Filter is used, the filter must be changed
according to its manufacturer's recommendations.
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
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
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:
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) 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
(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.
