SAE 15W-40 Heavy-Duty Diesel and Marine Oil (AME)

Amsoil SAE 15W-40 Heavy-Duty Diesel and Marine Oil (AME)

Product Highlights

Amsoil 15W-40 Synthetic Diesel and Marine Oil is engineered for pre-2007 diesel engines in on-road applications as well as all model year diesel engines in off-road applications. High 12 TBN controls acids from combustion blow-by and EGR. Additives control soot thickening, oxidation and wear. Extended drain capabilities reduce downtime and motor oil expenses.

PRODUCT DESCRIPTION

AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil is a premium diesel oil that provides excellent performance in all types of diesel engines where highly effective control of wear and deposits is vital. Engineered with heavy-duty dispersant/detergent additives, its Total Base Number (TBN) of 12 neutralizes acids and controls soot thickening from exhaust gas recirculation (EGR) and blow-by to protect against corrosion, cylinder bore polishing (wear), varnish and 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.

Longer Periods Between Oil Changes

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 chemistry deliver maximum engine protection, cleanliness and performance over extended drain intervals, reducing vehicle maintenance and waste-oil disposal costs.

Decreases Wear and Soot-Thickening Deposits

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 aggregating to form larger, wear-causing particles. Viscosity increase is minimized and soot-related wear is reduced.

Reduces Oil Consumption and Emissions

AMSOIL Series 3000 Diesel Oil is energy efficient for reduced fuel costs. Its low viscosity minimizes “drag” associated with high-viscosity oils, allowing the engine to operate more freely, maximizing power and fuel economy.

Premium Cold-Flow Properties

AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil eases cold-weather starting (down to -44°F) and provides vital startup lubrication to help prevent engine wear. AMSOIL Synthetic Heavy Duty Diesel Oil outperforms conventional 15W-40 petroleum oils and minimizes the impact of cold-weather operation.

Excellent Performance in High Temperatures

AMSOIL Series 3000 Diesel Oil resists thermal (heat) breakdown, oxidation and sludge formation better than conventional oils. And unlike conventional petroleum oils, AMSOIL Series 3000 contains no wax. It stays fluid down to -50°C (-58°F) for improved cold-temperature oil flow, reduced bearing wear and easier starting.

APPLICATIONS

AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil 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 diesels equipped with EGR systems.

AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil is recommended for diesel engines, gasoline engines and other applications that require any of the following specifications:

  • SAE 15W-40
  • ACEA A3/B3, E2, E3, E5, E7
  • GAPI CI-4+/CI-4/CH-4/CF/CF-2/SL/SJ
  • JASO DH-1
  • Global DHD-1
  • Mack EO-M, EO-N
  • DDC 93K214
  • Caterpillar ECF-1A, ECF-2
  • Cummins CES 20076, 20077, 20078
  • Volvo VDS-2, VDS-3
  • MTU Type 2
  • MB 228.1, 228.3, 229.1
  • MAN 271, 3275

COMPATIBILITY

AMSOIL Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil is compatible with other conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil's 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 and Marine Motor Oil is recommended for extended drain intervals in unmodified, mechanically-sound vehicles or equipment as follows:

Diesel Engine Service

  • 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.

*Operating conditions and drain intervals for severe and normal service are defined by the OEM. Refer to your owner’s manual.
