PRODUCT DESCRIPTION
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 15W-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.

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

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.
