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).
Less High-Temperature Evaporation With AMSOIL
Lower Cold-Temperature Flow Properties With AMSOIL
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
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.
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
(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
