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 15W-40 Diesel Oil 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 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 maximum 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 is designed to keep soot particles suspended independently and prevent 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 Diesel & Marine Motor Oil 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 15W-40 Diesel Oil 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. AMSOIL Synthetic Heavy Duty Diesel Oil outperforms conventional 15W-40 petroleum oils and greatly minimizes the impact of cold weather operation.Applications
AMSOIL AME is engineered for use in a wide variety of light and heavy-duty 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 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 15W-40 Heavy Duty Diesel and Marine Motor Oil (AME) is recommended for extended drain intervals in engines that are unmodified and in good operating condition.Diesel Engine Service
*Operating conditions and drain intervals for severe and normal service are defined by the OEM. Refer to your owner’s manual.
- Three times (3X) OEM* recommendation, not to exceed 50,000 miles/600 hours or one year, whichever comes first. Drain intervals may be extended further with oil analysis.
- Gasoline Engine Service
- Two times (2X) OEM* recommendation, not to exceed 15,000 miles or one year, whichever comes first.
Note: Extended drain intervals are not recommended when using biofuels containing >10% ethanol or 5% biodiesel (B5). Follow OEM drain intervals or extend drain intervals with oil analysis.
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 Ea By-pass oil filters are specialized for the removal of small, wear-causing dirt particles, thereby extending engine life. AMSOIL encourages using an AMSOIL Ea By-pass filter system for maximum engine and oil life.Oil Analyzers Inc. (715-395-0222) is a division of AMSOIL that provides cost-effective, quality oil analysis services.Health & Safety
