Protects Your Engine
AMSOIL Signature Series Synthetic Motor Oil
provides outstanding anti-wear protection. It develops a strong
fluid film that keeps metal surfaces separated while its robust
anti-wear additives further reduce wear in metal-to-metal contact
regions for maximum engine life. In the Sequence IIIG test, which is
normally run for 100 hours, AMSOIL Signature Series Synthetic Motor
Oil delivered outstanding wear protection for the camshaft and
lifters, even after doubling the test interval to 200 hours. For
details, see the
Double-Length Sequence IIIG Engine Test Technical Study.
Maximizes Fuel Economy
Signature Series Synthetic Motor Oil is
designed to maximize energy efficiency for optimum 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
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 is designed to deliver
outstanding engine protection, cleanliness and performance over
extended drain intervals. It reduces vehicle maintenance and waste
Keeps Pistons Clean
deposits can lead to pre-ignition and engine knocking, which results
in lost power, reduced fuel economy and, in severe cases, engine
damage. Signature Series' premium additives and naturally high
resistance to extreme heat help keep pistons clean for maximum
engine performance. After a double-length, 200-hour Sequence IIIG
engine test, Signature Series demonstrated outstanding cleanliness
properties and shattered the requirements of a 100-hour test.
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.
Reduces Oil Consumption and Emissions
Volatility (burn-off) occurs when oil gets hot,
causing high oil consumption and emissions. Signature Series resists
volatility better than other oils, helping reduce oil consumption
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
API SN (Resource Conserving), SM…; ILSAC GF-5, GF-4…; ACEA A5/B5,
A1/B1; Chrysler MS-6395; GM dexos1™ (supersedes LL-A-025, 6094M and
4718M) Fortified with detergents that exceed dexos1 sulfated ash
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 its 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.
Normal Service – Up to
25,000 miles, 700 hours of operation or one year, whichever
comes first, in personal vehicles not operating under Severe
Severe Service – Up to
15,000 miles, 700 hours of operation or one year, whichever
Severe Service: Primarily
short trips (less than 10 miles [16 km]); turbo/supercharged
engines; commercial or fleet vehicles; excessive idling; first-time
use of AMSOIL motor oil in a vehicle with more than 100,000 miles;
frequent towing, hauling, plowing or driving in dusty conditions.
Modified engines (non-stock) and those
using E85 fuel are excluded from extended drain recommendations.
Change at the vehicle manufacturer’s
recommended drain interval outside U.S. and Canada.
AMSOIL Ea® Full-Flow Oil Filters are
designed for extended change intervals. With other brands, do
not exceed six months or 10,000 miles unless longer intervals
are recommended by the vehicle manufacturer.
Check oil regularly to maintain proper fill
full-flow oil filters are designed for extended drain intervals.
They stop smaller particles, flow more oil and last longer than
regular filters. For best performance, use AMSOIL full-flow oil
