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

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.
