AMSOIL 100% Synthetic 0W-20 Motor Oil (ASM) delivers extraordinary lubrication for automotive gasoline engines.
AMSOIL combined the industry premier synthetic technology and additives into a light viscosity formulation that
withstands high temperatures and delivers outstanding fuel economy and cold temperature performance. AMSOIL ASM
replaces SAE 5W-20 and is recommended for extended drain intervals according to AMSOIL service interval
guidelines. 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 Synthetic 0W-20 Motor Oil can extend drain intervals far beyond those recommended for conventional oils.
Its unique synthetic formulation and long drain additive system are very stable, resisting oxidation and
neutralizing acids. AMSOIL ASM delivers the best possible engine protection, cleanliness and performance over
extended drain intervals, reducing vehicle maintenance and waste oil disposal costs.
Maximizes Fuel Economy
AMSOIL Synthetic 0W-20 Motor Oil is designed to maximize energy efficiency for improved fuel economy. Its light
viscosity properties reduce drag and its uniform molecular structure helps it flow more freely to lower
friction between metal surfaces. Anti-friction additives are included to further improve energy efficiency.
Protects Against Wear
AMSOIL Synthetic 0W-20 Motor Oil is a shear stable formulation with a high viscosity index. It provides
excellent viscosity film strength to separate metal surfaces and contains robust anti-wear additives for the
best possible engine protection.
Reduces Oil Consumption and Emissions
Volatility (burn-off) occurs when oil gets hot, causing high oil consumption and emissions. AMSOIL Synthetic
0W-20 Motor Oil has a very low volatility rate, making it excellent at controlling volatility related oil
consumption and emissions.
Excels in Extreme Temperatures
AMSOIL Synthetic 0W-20 Motor Oil resists thermal breakdown better than conventional oils. It is heavily
fortified with detergent and dispersant additives to prevent sludge deposits and keep engines clean. And unlike
conventional oils, AMSOIL ASM contains no wax. It stays fluid down to -65°F for improved cold temperature oil
flow, reduced bearing wear and easier starting.
AMSOIL Synthetic 0W-20 Motor Oil is recommended for Honda, Acura, DaimlerChrysler, Toyota, Ford and all other
applications where SAE 0W-20 or 5W-20 is required with the following specifications:
API SM/CF, SL, SJ. . .
ILSAC GF-4, 3. . .
AMSOIL ASM is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils,
however, will shorten the oil life expectancy and reduce the performance benefits of AMSOIL. AMSOIL does not
support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended for
use with AMSOIL motor oils.
AMSOIL Synthetic 0W-20 Motor Oil is recommended for extended drain
intervals in unmodified(1), mechanically sound(2) gasoline-fueled vehicles as
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.
Replace AMSOIL Ea oil filter at the time of oil change up to 25,000 miles or one year, whichever
comes first (other brands at standard OEM* intervals).
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 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
(2) Mechanically sound engines are in good working condition and do not, for example, leak
oil or consume excessive amounts, are not worn out, do not overheat, do not leak anti-freeze and have properly
working emission control systems. AMSOIL recommends repairing malfunctioning engines prior to the installation
of AMSOIL synthetic oils.
(3) Personal vehicles frequently traveling greater than 10 miles (16km) at a time and not
operating under severe service.
(4) Turbo or supercharged vehicles, commercial or fleet vehicles, extensive engine idling,
first and subsequent use of AMSOIL in vehicles with over 100,000 miles, daily short trip driving less than 10
miles (16km), frequent towing, plowing, hauling or dusty condition driving.
AMSOIL Ea Full-Flow 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
