AMSOIL Synthetic 5W-40 Premium Diesel Oil is
the premium choice diesel oil for model year 2007 and newer heavy-duty
and pickup truck diesel engines requiring API CJ-4 emission quality
AMSOIL Synthetic 5W-40 (DEO) 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 Synthetic 5W-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
Synthetic 5W-40, with its broad viscosity range, is ideal for
winter and summer use. It resists breakdown and can extend drain
intervals when monitored by oil analysis.
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 5W-40 Diesel Oil is a low sulfated
ash formulation that exceeds the modern requirements for low emission
quality diesel oil. It is compatible with all exhaust treatment
devices and is designed to extend the service life of particulate
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.
Maximizes Fuel Economy and Reduces Oil Consumption
AMSOIL Synthetic 5W-40 Premium Diesel Oil has
a very low high temperature volatility rate (burn off). Because
less oil vapor passes into the combustion chamber, oil consumption
and emissions are reduced. Additionally, lower volatility helps
AMSOIL Synthetic 5W-40 retain its viscosity after high temperature
service for continued dependable protection and excellent fuel
Excels in Extreme Temperatures
AMSOIL Synthetic 5W-40 Premium Diesel Oil resists
thermal (heat) breakdown, oxidation and sludge formation better
than conventional petroleum oils. And unlike conventional oils,
AMSOIL 5W-40 contains no wax. It stays fluid in cold temperatures
for improved oil flow, reduced bearing wear and easier starting.
AMSOIL Synthetic 5W-40 Premium Diesel Oil replaces
5W-40, 10W-40 and 15W-40 viscosity oils. It is backwards
compatible with pre-2007 diesel engines and recommended
for newer and older diesel and gasoline engines and other applications
requiring the following worldwide specifications:
API CJ-4, CI-4+, CH-4, CF
API SM, SL, SJ...
Mack EO-O Premium Plus
DDC Power Guard 93K218
Caterpillar ECF-3, ECF-1
Cummins CES 20081
MTU Type II
AMSOIL Synthetic 5W-40 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 Synthetic 5W-40 Premium Diesel Oil is
recommended for use according to the longest service interval
established by the engine, vehicle or equipment manufacturer.
Drain intervals may be extended when monitored by 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.
