THE Ultimate in Diesel Engine Protection and Fuel Efficiency.
Outstanding synthetic lubrication provides unbeatable wear protection and maximum diesel fuel economy. Extended drain capability reduces downtime and diesel motor oil expenses.

Designed to deliver 1,000,000 miles in over the road trucks
before engine overhaul.

Exceeds the stringent performance specifications of all major American and European truck manufacturers.

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 expensive diesel engine.

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.

Conventional diesel oils become thicker in only a few thousand miles which increases engine drag and reduces fuel economy. AMSOIL Synthetic 15W-40 Diesel Oil retains its viscosity providing excellent fuel economy and dependable protection.

Class 8 Diesel Trucks Achieve 8.2% Better Fuel Economy with Amsoil Lubricants

COST EFFECTIVE
This superior synthetic diesel oil costs a few dollars more but lasts far longer than other diesel oils. This can save you 50% on oil change expenses. And you can add the savings from better fuel economy on top of that. You get maximum performance, improved fuel economy and lower maintenance costs.

Extends Drain Intervals

ENDURANCE AIR & OIL FILTERS


AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil 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 high temperature volatility (evaporation) than conventional 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 improved fuel economy and continued dependable protection.

Excellent Cold Flow Properties
It eases cold weather starting and provides vital startup lubrication to prevent engine wear.

AMSOIL AME remains fluid down to -44°F

AME outperforms conventional 15W-40 petroleum oils and greatly minimizes the impact of cold weather operation.

APPLICATIONS
AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil is engineered for use in a wide variety of light and heavy-duty diesel engines, including over-the-road trucks, off road construction, marine engines, farm equipment, mining, industrial (pumps & generators) and personal automotive or commercial transportation. It is excellent for use with low or high sulfur diesel fuels in standard, turbocharged or supercharged diesel engines, including modern low emission diesels such as those equipped with EGR systems.

AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil is recommended for use in diesel engines and other applications requiring any of the listed worldwide specifications and gasoline engines requiring

RECOMMENDED OIL FILTERS
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 and oil life.

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:

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 OEM* recommended interval.

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.

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 or Donaldson Endurance™ ELF 7349 at the time of oil change up to 25,000 miles (other brands at standard OEM* intervals).

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) Where the engine or operating conditions have been modified from the original manufacturers' design, no oil change interval recommendation is made. Oil change intervals are at the owner's discretion. Examples include the use of performance computer chips; modified exhaust, fuel or air induction systems and the use of fuels other than those recommended for normal operation by the manufacturers.

(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 antifreeze 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 or hauling heavy loads and frequent driving in dusty conditions.
