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
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
Maximizes Fuel Economy, Reduces Oil Consumption and
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
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 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 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 API

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.

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
