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
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 chemistry deliver maximum engine protection,
cleanliness and performance over extended drain intervals, reducing vehicle
maintenance and waste-oil disposal costs.
Controls Soot and Wear
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 Synthetic Heavy Duty Diesel & Marine Motor Oil has lower volatility than
conventional petroleum oils. Oil consumption and emissions are minimized due to
less vapor passing into the combustion chamber. Lower volatility helps AMSOIL
15W-40 Diesel Oil retain its viscosity after high-temperature service for continued
Excellent 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.
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
- API CI-4+/CI-4/CH-4/CF/CF-2/SL/SJ
- ACEA A3/B3, E2, E3, E5, E7
- Global DHD-1
- JASO DH-1
- Mack EO-M, EO-N
- DDC 93K214
- Caterpillar ECF-1A, ECF-2
- Cummins CES 20076, 20077, 20078
- Volvo VDS-2, VDS-3
- MB 228.1, 228.3, 229.1
- MAN 271, 3275
- MTU Type II
AMSOIL Synthetic Heavy Duty Diesel & Marine Oil is compatible
with conventional and synthetic motor oils. Mixing AMSOIL
motor oils with other oil, 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.
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.
Note: Extended drain intervals are not recommended when using biofuels containing >10% ethanol or 10% biodiesel (B10).
Follow OEM drain intervals or extend drain intervals with oil analysis.
