Synthetic Heavy-Duty Diesel & Marine Motor Oil SAE 15W-40
(AME)

Engineered for all types of diesel engines with an emphasis on
modern, low emission heavy duty diesel engines. High 12 TBN
controls acids from combustion blow-by and EGR. High levels of
detergency and dispersancy additives control soot thickening,
oxidation and wear. Resists bore polishing, deposit formation and
ring sticking. Provides clean engine performance. Extended drain
capabilities reduce downtime and motor oil expenses.

PRODUCT DESCRIPTION
AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil (AME) is a premium diesel oil providing
excellent performance in all types of diesel engines where highly effective control of wear and deposits
is vital. Built with heavy-duty dispersant/detergent additives, its 12 TBN chemistry neutralizes acids
and controls soot thickening from EGR and blow-by to protect against corrosion, cylinder bore
polishing (wear) and varnish/sludge deposits. AMSOIL AME resists heat and breakdown better than
conventional petroleum oils for 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 AME can extend drain intervals far beyond those recommended for conventional petroleum
oils. Its unique synthetic formulation and long drain additive system deliver the best possible engine
protection, cleanliness and performance over extended drain intervals, reducing vehicle maintenance
and waste oil disposal costs.

Advanced Soot and Wear Control Formula
AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil is heavily fortified with detergent/dispersant
additives and is naturally resistant to soot. It keeps soot particles suspended independently,
preventing them from attaching together to form larger, wear-causing particles. Viscosity increase is
minimized and soot related wear is controlled.

Maximizes Fuel Economy, Reduces Oil Consumption and Emissions
AMSOIL AME has lower volatility (evaporation) than con-ventional petroleum oils. Because less oil
vapor passes into the combustion chamber, oil consumption and emissions are reduced. Lower
volatility helps AMSOIL AME retain its viscosity after high temperature service for excellent fuel
economy and continued dependable protection.

Excellent Cold Flow Properties
AMSOIL AME remains fluid down to -44°F. It eases cold weather starting and provides vital start-up
lubrication to prevent engine wear. AME outperforms conventional 15W-40 petroleum oils and greatly
minimizes the impact of cold weather operation.

AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil is engineered for use in a wide variety of
light and heavyduty applications, including over-the-road trucks, off road construction, marine
commercial transportation. It is excellent for use with low or high sulfur diesel fuels in standard,
turbocharged or supercharged engines, including modern low emission diesels such as those

MIXING AMSOIL
AMSOIL AME 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 Heavy Duty Diesel & Marine Motor Oil is recommended for extended drain intervals
in unmodified(1), mechanically sound(2) vehicles or equipment as follows:

Personal Light Truck Diesel Engine Service

• Normal Service(3) -- Up to 25,000 miles or one year, whichever comes first, or longer based on oil
analysis.

• Severe Service(4) -- Up to 15,000 miles or one year, whichever comes first, or longer based on oil
analysis.

• Replace AMSOIL Ea™ full flow oil filter at the time of oil change up to 25,000 miles (other brands at
standard OEM* intervals).

Commercial or Fleet Vehicles, Long-Haul Trucks, Marine Craft, RV, Off-Road Equipment

• Non-EGR equipped diesels -- extend drain intervals up to two times (2X) the OEM* recommended
drain interval or one year, whichever comes first, or longer based on oil analysis.

• EGR equipped or low emission diesels -- extend drain intervals based on oil analysis or use the
longest drain recommendation of the OEM*.

• Replace Donaldson Endurance™ or AMSOIL Ea™ full flow oil filters at the time of oil change up to
two times (2X) longer than the OEM* standard interval, not to exceed 60,000 miles in long-haul trucks.

Gasoline Engine Service

• In gasoline engines, oil drain intervals may be extended up to two times (2X) the OEM*
recommended drain interval (not to exceed 15,000 miles without oil analysis) or one year, whichever
comes first. Replace AMSOIL Ea™ full flow filter at the time of oil change up to 25,000 miles. Replace
other brand oil filters at standard OEM* intervals.

*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 manufacturer.

(2) Engines are in good working condition and within the factory design settings. Mechanically sound
engines, for example, do not leak oil or consume excessive amounts, are not worn out, do not
overheat, do not have internal or external anti-freeze leaks and have a properly working emission
control system. AMSOIL recommends repairs be made to malfunctioning engines prior to the
installation of AMSOIL synthetic oils.

(3) Personal transportation vehicles frequently traveling greater than 10 miles (16 km) at a time and
not operating under severe service.

(4) Extensive engine idling, daily short trip driving less than 10 miles (16 km), frequent towing,
plowing, hauling heavy loads or dusty-condition driving.

AMSOIL Ea™ and Donaldson Endurance™ full flow oil filters are designed for extended drain
intervals. They stop smaller particles, have less restriction and last longer than regular filters. For
best performance, use AMSOIL Ea or Donaldson Endurance oil filters.

AMSOIL by-pass oil filters are specialized for the removal of small, wear-causing dirt particles,
thereby extending engine life. AMSOIL encourages using an AMSOIL bypass filter system for
maximum engine and oil life.
