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.

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.

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

Maximizes Fuel Economy, 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.

COMPATIBILITY

AMSOIL Synthetic Heavy Duty Diesel and Marine Oil 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 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 5% biodiesel (B5). Follow OEM drain intervals or extend drain intervals with oil analysis.

HEALTH & SAFETY

This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

The value of a Classic.

Greetings,

I have a 2001 Hummer H1 and I recently 'rescued' a 1995 Hummer H1. Now, both of these vehicles are
getting closer to the Classic status. I am bringing the 1995 back to life. I have changed the diff oil, hub oil, engine oil, trans oil, and coolant with Amsoil. The 1995 is running strong now.

I take the vehicles out in the wilderness. I see no reason to risk my family getting stranded by using a cheap/sub-standard product.

Adventure on!

Excellent product!

I've been using Amsoil 15W-40 Heavy-duty Diesel and marine oil in my 2006 Silverado 2500HD for 10 years now. Oil and filter change intervals average around 12,000 to 18,000 miles.
The truck now has over 355,000 miles on it and it still runs great! I never have to add any oil between oil changes either. If you are on the fence about using this oil in your vehicle, I say, go for it! You won't regret it!
Amsoil is top of the line!

15W40 Heavy Duty Diesel Oil

I have an 06 Dodge with the Cummins. These 'older' diesels required a CI4+ oil. There is much debate in the oil world about the qualities of the newer oils vs the older ones - specifically that the old CI4+ oils had more detergents in them, which the older engines liked better. Even though the newer oils are backwards compatible, they apparently do not have the same detergents in them. This has been the only CI4+ rated oil I can still find. Its the only oil I use in the Cummins.

15w40 he diesel oil

Used this oil for 27 years and never had a oil leak or any engine failure. Put 300,000 miles on Dodge TURBO Cummins, check but never had to adjust valves. Only oil I will use.

The best oil.

I maintain seven vehicles so changing oil could be a full time job. I use Amsoil because it is the best oil made and the best filter in the industry. My twin sons just became 16. For their birthday I had them learn how to change the oil in their trucks by converting them to Amsoil . This oil seems to be better suited to my older VW Jetta than the other Diesel oils. I use less of this oil. My car has nearly 300,000 miles and has always used about 4 oz of oil every 500 miles. With this oil that amount is cut in half.

Amsoil is THE way to go!

When I first heard about Amsoil I was really surprised by the quality of ALL of Amsoil's products. Amsoil strives to produce the best product for the most efficiency, longevity, and power from any engine. My first oil change using Amsoil after I started up my truck and got all the new oil moving around I noticed my 260,000 mile 6.0 Powerstroke ran smoother and I can rely on Amsoil to keep my old ford running like new for years to come. All I use is Amsoil in all of my vehicles.

I started using this oil after the break in period and have used it with an Amsoil #099 Filter changing both each year and it seems to do very well. The truck neither leaks or burns any oil since I purchased it in January 2000.
