Lubricant Viscosities
(Fluids Recommendations)
General Information for Lubricants
When you are operating the machine in
temperatures below 20C4F), refer to Special
Publication, SEBU5898, “Cold Weather
Recommendations for all Caterpillar Machines”. This
publication is available from your Cat dealer.
For cold-weather applications where transmission
oil SAE 0W-
20
is recommended, Cat Cold Weather
TDTO is recommended.
Refer to the “Lubricant Information” section in the
lat
est
revision of the Special Publication, SEBU6250,
“Caterpillar Machine Fluids Recommendations” for a
list of Cat engine oils and for detailed information.
This manual may be found on the Web at
Safety.Cat.com.
The footnotes are a key part of the tables. Read ALL
f
ootno
tes that pertain to the machine compartment
in question.
Selecting the Viscosity
In order to select the proper oil for each machine
compartment, refer to the “Lubricant Viscosity for
Ambient Temperature” table. Use the oil type AND
oil viscosity for the specific compartment at the
proper ambient temperature.
The proper oil viscosity grade is determined by the
minim
um am
bien
t temperature (the air in the
immediate vicinity of the machine). Measure the
temperature when the machine is started and while
the machine is operated. In order to determine the
proper oil viscosity grade, refer to the “Min” column
in the table. This information reflects the coldest
ambient temperature condition for starting a cold
machine and for operating a cold machine. Refer to
the “Max” column in the table for operating the
machine at the highest temperature that is
anticipated. Unless specified otherwise in the
“Lubricant Viscosities for Ambient Temperatures”
tables, use the highest oil viscosity that is allowed for
the ambient temperature.
Machines that are operated continuously should use
oils
th
at have the higher oil viscosity in the final
drives and in the differentials. The oils that have the
higher oil viscosity will maintain the highest possible
oil film thickness. Refer to “General Information for
Lubricants” article, “Lubricant Viscosities” tables,
and any associated footnotes. Consult your Cat
dealer if additional information is needed.
NOTICE
Not following the recommendations found in this
man
ual can lead to reduced performance and
compartment failure.
Engine Oil
Cat oils have been developed and tested in order to
provide the full performance and life that has been
designed and built into Cat engines.
Cat DEO-ULS or oils that meet the Cat ECF-3
sp
ecifi
cation and the API CJ-4 are required for use
in the applications listed below. Cat DEO-ULS and
oils meeting Cat ECF-3 specification and the API CJ-
4 and ACEA E9 oil categories have been developed
with limited sulfated ash, phosphorus, and sulfur.
These chemical limits are designed to maintain the
expected aftertreatment devices life, performance,
and service interval. If oils meeting the Cat ECF-3
specification and the API CJ-4 specifications are not
available, oils meeting ACEA E9 may be used.
ACEA E9 oils meet the chemical limits designed to
maintain aftertreatment device life. ACEA E9 oils are
validated using some but not all ECF-3 and API CJ-4
standard engine performance tests. Consult your oil
supplier when considering use of an oil that is not
Cat ECF-3 or API CJ-4 qualified.
Failure to meet the listed r
equir
ements will damage
aftertreatment-equipped engines and can negatively
impact the performance of the aftertreatment
devices. The Diesel Particulate Filter (DPF) will plug
sooner and require more frequent DPF ash service
intervals.
Typical aftertreatment systems
include the following:
•
Diesel Particulate Filters (DPF)
• Diesel Oxidation Catalysts (DOC)
• Selective Catalytic Reduction (SCR)
• Lean NOx Traps (LNT)
Other systems may apply.
