AMSOIL Premium 5W-40 Synthetic Diesel Oil 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 best additive and synthetic base oil technology, AMSOIL Premium 5W-40 Synthetic
Diesel Oil exceeds the higher performance demands of modern engines. It
withstands the stress of heat, soot and acids to help prevent deposits, wear
and corrosion. AMSOIL Premium 5W-40 is wax-free with a broad viscosity
range to provide exceptional cold-weather starting and high-temperature
protection. It resists breakdown and offers maximum fuel efficiency over
extended drain intervals.
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.
Meets Emission System Requirements
AMSOIL Premium 5W-40 Synthetic Diesel Oil is a low-sulfated
ash formulation that exceeds the
requirements for low-emission quality diesel oil. 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 5W-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
5W-40 Synthetic Diesel Oil provides
maximum protection for up to 3X the original equipment manufacturer
(OEM)-recommended drain interval
and even further with oil analysis.
Improves Fuel Economy
The advanced synthetic technology used
to engineer AMSOIL Premium 5W-40
Diesel Oil enhances viscosity properties and is proven to deliver better fuel
economy. In fact, the Environmental
Protection Agency’s (EPA) Federal Test
Procedure confirms that AMSOIL 5W-40
Diesel Oil provides up to 3 percent increased fuel economy over conventional
15W-40 diesel oils. When driving at a mix
of 55 percent city/45 percent highway, the
average improvement is 1.6 percent and
at straight highway driving the average
improvement is 1.25 percent.
Minimizes Oil Consumption and Emissions
Due to its low rate of volatility, AMSOIL
5W-40 Synthetic Diesel Oil is able to
reduce oil consumption and emissions
during operation. Lower volatility helps
AMSOIL Premium Diesel Oil retain its
viscosity after high-temperature service
for dependable protection and excellent
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.
AMSOIL Premium 5W-40 Synthetic Diesel Oil is recommended
for diesel engines and, where appropriate, gasoline engines
requiring any of the following specifications:
- SAE 5W-40
- API Licensed CJ-4, CI-4+, CF, SN, SM
- ACEA E7, E9
- Mack EO-O
- DDC 93K218
- Caterpillar ECF-3, ECF-2, ECF-1-a
- Cummins 20081
- Volvo VDS-4, VDS-3
- MS 10902
- MB 228.31
- MTU Type I & II, Type 2.1
- MAN 3275, 3575
- JASO DH-2
- Global DHD-1
- Renault RLD-3
- Ford WSS-M2C171E
AMSOIL Premium 5W-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.
AMSOIL Premium 5W-40 Synthetic Diesel 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.
- 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.
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.
