PRODUCT DESCRIPTION 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).

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.
