AMSOIL Synthetic 15W-40 Diesel Oil (DME) is the premium choice for API CJ-4 emission-quality diesel oil required by model-year 2007 and newer diesel engines. It delivers extraordinary lubrication in diesel engines found in commercial, fleet and personal vehicles. Built with the latest additive and synthetic base oil technology, AMSOIL Premium Synthetic 15W-40 Diesel Oil exceeds the higher performance demands of modern engines. It withstands the stress of heat, soot and acids to help prevent deposits, corrosion and wear.

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.

Exceeds Emission System Requirements

AMSOIL Synthetic 15W-40 Diesel Oil is a low-sulfated ash formulation that provides excellent performance in low-emission diesel engines. It is compatible with all exhaust treatment devices and is designed to extend the service life of diesel particulate filters (DPF).

Extended Drain Performance

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

Controls Soot Thickening and Wear

The advanced synthetic base oils in AMSOIL 5W-40 Diesel Oil are naturally resistant to soot contamination. 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.

Superior Shear Stability, Reduced Oil Consumption

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

Ideal 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.

Based on 120,000 miles per year with an OEM-recommended drain interval of 10,000 miles. Does not include labor, filter, or used oil disposal costs, making AMSOIL even more cost effective.

Applications

AMSOIL Premium CJ-4 Synthetic 15W-40 Diesel Oil is recommended for diesel engines and, where appropriate, gasoline engines requiring any of the following specifications:

• SAE 15W-40
• API CJ-4, CI-4+, CF, SM
• ACEA E7, E9
• Mack EO-O Premium Plus
• DDC Power Guard 93K218
• Caterpillar ECF-3, ECF-2
• Cummins 20081

• MAN 3275
• JASO DH-2
• Global DHD-1
• Renault RLD-3

Compatibility

AMSOIL Synthetic 15W-40 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 Synthetic 15W-40 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.

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.

AMSOIL Ea and Donaldson Endurance full flow oil filters are designed for extended drain intervals. They stop smaller particles, have less restriction and last longer than regular filters. For best performance, use AMSOIL Ea or Donaldson Endurance oil filters.

AMSOIL Ea By-pass oil filters are specialized for the removal of small, wear-causing dirt particles, thereby extending engine life. AMSOIL encourages using an AMSOIL Ea By-pass filter system for maximum engine and oil life.
