PRODUCT
DESCRIPTION AMSOIL 100% Synthetic 5W-30 Motor Oil (ASL)
delivers extraordinary lubrication in all types of automotive
gasoline engines. By combining the industry premier synthetic
technology with AMSOIL premium additives, AMSOIL ASL exceeds
the higher performance demands of modern engines. It withstands
the stress of higher horsepower, higher heat and complicated
emission control systems. AMSOIL Synthetic 5W-30 Motor Oil
consistently outperforms 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 Synthetic 5W-30 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 ASL 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 5W-30 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 AMSOIL Synthetic 5W-30 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 Synthetic 5W-30 Motor Oil
has the lowest volatility rate of the oils tested, making it
the best at controlling volatility-related oil consumption and
emissions (see chart below).
Excels in Extreme
Temperatures
AMSOIL Synthetic 5W-30 Motor Oil resists thermal (heat)
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 ASL contains no wax. It stays fluid down to -58°F
for improved cold temperature oil flow, reduced bearing wear
and easier starting (see chart below).

APPLICATIONS
AMSOIL Synthetic 5W-30 Motor Oil is recommended for gasoline
engines, diesel engines (API CF, ACEA B5) and other
applications requiring any of the listed worldwide
specifications:
- API SM/CF, SL, SJ ...
- ILSAC GF-4, 3 ...
- ACEA A5/B5-04 A1/B1
- JASO VTW
- GM 4718M, 6094M
- Ford WSS M2C929-A
- Daimler Chrysler MS-6395N
- VW 503.00
MIXING AMSOIL
AMSOIL ASL 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. AMSOIL does not support extended drain intervals
where oils have been mixed.
Aftermarket oil additives are not recommended
for use with AMSOIL motor oils.
SERVICE LIFE
AMSOIL Synthetic 5W-30 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.
• 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(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 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 (16 km) at a time and not operating under
severe service.
(4) Turbo/supercharged vehicles, commercial
or fleet vehicles, extensive engine idling, use of AMSOIL motor
oil in vehicles with more than 100,000 miles without prior 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 drain intervals. They stop smaller particles, flow
more oil and last longer than regular filters. For best
performance, use AMSOIL full-flow oil filters.
