AMSOIL OE 15W-40 Synthetic Diesel Oil provides excellent protection
and performance in both on- and off-road diesel engines for the original
equipment manufacturer’s recommended drain interval. It meets API
CJ-4 specifications and is suitable for both modern and older diesel applications.
AMSOIL OE 15W-40 Synthetic Diesel Oil exceeds the higher
performance demands of modern engines and withstands the stress of
heat, soot and acids to help prevent deposits, wear and corrosion.
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 OE 15W-40 Synthetic Diesel Oil is a low-sulfated ash formulation that meets
the requirements for low-emission quality diesel oil and protects under the most severe
conditions found in modern diesel engines. It is compatible with all exhaust treatment
devices and is designed for engines equipped with diesel particulate filters (DPF).
AMSOIL OE 15W-40 Synthetic Diesel Oil is formulated for improved heat and
oxidation resistance over conventional petroleum oil for cleaner engine operation,
maintaining power and fuel efficiency for superior engine performance. Its dependable
cold-temperature flow assures easier start-up and improved post start-up protection.
Resists Oil Consumption and Emissions
Due to its low rate of volatility (burn-off), AMSOIL OE 15W-40 Synthetic Diesel Oil
is able to reduce oil consumption and emissions during operation. It maintains its
excellent film strength even during high-temperature operating conditions to ensure
dependable protection, performance and fuel efficiency.
Controls Soot-Thickening and Wear
AMSOIL OE 15W-40 Synthetic Diesel Oil is formulated with premium synthetic base
stocks and robust detergent/dispersant additives that keep soot particles from
agglomerating and forming larger wear-causing particles. The AMSOIL OE 15W-40
Synthetic Diesel Oil formulation allows for optimal soot-related viscosity control to
maintain stay-in-grade performance.
AMSOIL OE 15W-40 Synthetic Diesel Oil is recommended for
diesel engines and, where appropriate, gasoline engines
requiring any of the following specifications:
- API CJ-4, CI-4+, SM...
- ACEA E9
- DDC 93K218
- Cummins CES 20081
- MB 228.31
- CAT ECF-3, ECF-2, ECF-1-a
- Mack EO-O Plus
- Volvo VDS-4
- MAN 3575
- Renault RLD-3
- MTU Type 2.1
AMSOIL OE 15W-40 Synthetic Diesel Oil is compatible
with conventional and synthetic motor oils. Mixing AMSOIL
motor oils with other oils, however, will reduce the performance
Aftermarket oil additives are not recommended for use with
AMSOIL motor oils.
AMSOIL OE Synthetic Diesel Oil is recommended for the
intervals stated by the original equipment manufacturer
(OEM). Refer to the owner’s manual for the specific oil change
interval. Replace the oil filter at each oil change as specified
by the OEM.
