DME Meets Emission System Requirements

Amsoil 15W-40 Synthetic Diesel Oil is a low-sulfated ash formulation that meets the requirements for low-emission quality diesel oil and protects under the most severe conditions found in modern diesel engines. It is compatible with all exhaust treatment devices and is designed for engines equipped with diesel particulate filters (DPF).

Longer Drain Intervals

Amsoil Premium 15W-40 Synthetic Diesel Oil can extend drain intervals far beyond those recommended for conventional petroleum oils. Its unique synthetic formulation and long-drain additive system (10.4 TBN) deliver superior engine protection, cleanliness and performance over extended drain intervals. Amsoil 15W-40 Synthetic Diesel Oil provides maximum protection for up to 3X the OEM-recommended drain interval, even further with oil analysis.

Minimizes Oil Consumption and Emissions

Amsoil 15W-40 Synthetic Diesel Oil has lower volatility (burn-off) than conventional petroleum oils, resulting in less oil vapor passing into the combustion chamber, lowering oil consumption and emissions. Lower volatility helps Amsoil Premium Synthetic Diesel Oil retain its viscosity after high-temperature service for continued dependable protection.

Controls Soot-Thickening and Wear

The advanced synthetic base oils in Amsoil 15W-40 Synthetic Diesel Oil are naturally resistant to soot contamination and oxidative thickening. That, along with a heavy fortification of detergent/dispersant additives, keeps soot particles suspended independently, helping prevent the formation of larger, wear-causing particles. Viscosity increase is minimized and soot-related wear is controlled.

Perfect Setup for Fleets

Amsoil Premium 15W-40 Diesel Oil reduces operating costs through extended drain intervals. It is engineered for a wide range of applications, allowing fleet operators to consolidate engine oil inventories in mixed fleets. In addition, it reduces downtime through extended drain intervals and improved equipment protection.

COMPATIBILITY

Amsoil 15W-40 Synthetic Diesel 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 Premium CJ-4 15W-40 Synthetic Diesel Oil is recommended for extended drain intervals in engines that are unmodified and in good operating condition.

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.
  • 2007-2009 Caterpillar C13 and C15 on-highway engines must follow OEM drain interval.
  • 2007-Present Dodge, Ford and GM LMM light-duty diesel pickups must follow OEM-recommended drain interval. Drain intervals may be extended 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 normal and severe 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.
