Product Highlights View Full Description

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.

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.

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 dependable protection.

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.

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.

  • SAE 15W-40
  • API CI-4+/CI-4/CH-4/CF/CF-2/SL/SJ

COMPATIBILITY
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.

Absolutely great

Comments about SAE 15W-40 Heavy-Duty Diesel and Marine Oil:

I have used this oil from my first oil change at 5,000 miles with Amsoil absolute filters. Test oil at 25000miles change filter and run another 10000 miles. Tests have all came back with no viscosity breakdown, no metals or any other abnormalities. I now have 160,000 miles and have never had to add any oil other than what it takes to fill the filter. The service is second to none and so are Amsoil products.

Comments about SAE 15W-40 Heavy-Duty Diesel and Marine Oil:

Exceeds expectations. Ordinarily, when I used other motor oils discoloration takes place within 1 to 2000 miles. Thus far since I switched to Amsoil, 3000 miles, no discoloration and no oil consumption.

Comments about Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil:

I wouldn't crank up my 2001 Powerstroke 7.3 diesel without Series 3000 in the crankcase !! It's amazing protection, and allows me to only change oil when needed. The auxillary remote filtration system I purchased from Amsoil allows me years of worry-free protection !!!! NOTHING better !!!!

Verified Buyer

Comments about Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil:

I've been using using this product in my 2001 Ford Excursion 7.3L Diesel. Change every 15,000 miles . 288,000 miles so far ! High pressure oil actuates the fuel injectors on this engine. Still on original injectors. I believe the full synthetic oil has helped extend the life of the injectors. Several of my friends have had to replace their injectors on similar Ford diesels. Looking to put 500k miles on my Excursion. Amsoil products in transmission and rear end as well.
