An Omaha Long Time Favorite – Diesel and Marine 15W-40
A Diesel Formulation Frozen in Time (Pre 2008 diesels)
The diesel and marine 15W-40 oil has been AMSOIL’s big draw to the brand since it came out in 1976. Still regarded as the best choice for all non-DPF equipped diesel engines built before 2007, or any heavy-duty diesel engine built before diesel particulate filters were mandated.
The AMSOIL 15W-40 Diesel & Marine (product code AME) is robust with powerful detergents and a higher more lasting ZDDP zinc formulation than competing oils as it’s based on the pre-2008 emission changes.
We still get numbers of classic car owners with flat tappet cams who simply want to use a diesel oil, so this is the one fully formulated as they were when you bought them in the 80’s.
Premium diesel oil providing excellent performance in diesel engines where highly effective control of wear and deposits is vital. Built with heavy-duty dispersant/detergent additives with 12 TBN, Synthetic Heavy-Duty Diesel & Marine Oil neutralizes acids and controls soot thickening from EGR and blow-by to protect against corrosion, cylinder bore polishing (wear) and varnish/sludge deposits. It resists heat and breakdown and is formulated for extended drain intervals.

Years ago, AMSOIL astonished fleet owners with the refuse truck fleet study showing the common Rotella lasting a solid 300 hours under severe service but the AMSOIL AME 15W-40 outlasted 900 hours w/o any change of viscosity and caused the 8000-hour overhaul to be skipped. The drivers all were impressed and trucks which didn’t get plugged into the block heaters were OK for starting the next morning (Test done in Duluth over all seasons). Drivers also noted the significant improvements in the hydraulic operation using AMSOIL’s best AW series multi-viscosity oil.
Should really be the best-selling oil in the Omaha area for those who want to keep and preserve their older diesel work trucks avoiding the newer models which are a fuel economy and service department nightmare.

Controls Soot and Wear
AMSOIL Synthetic Diesel and Marine 15W-40 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.
Excellent Cold-Flow Properties
AMSOIL Synthetic 15W-40 Diesel and Marine 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.
AME 15W-40 Diesel and Marine 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.
