Notes on engine oils
!
Use only engine oils with the specified
grade.
Observe the safety notes on service products
(

The quality of the engine oil is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Benz approves
engine oils that correspond to the current
technical standard.
Vehicles with a diesel engine: only use
engine oils which correspond to Mercedes-
Benz Specifications for Service Products,
Sheet No. 228.61.
Engine oils according to Sheet No. 228.61
have a higher quality standard and have a
favorable effect on:
R
length of oil change interval
R
engine wear
R
fuel consumption
R
exhaust emissions
i
You can find information on the quality
grade, e.g. Sheet No. 228.61, and the vis-
cosity, e.g. SAE class 5W-30, on the oil con-
tainer.
Engine oil according to Sheet No. 228.61 and
SAE class 5W-30 will be filled before delivery.
Scope of use
Multi-grade engine oils that comply with Sheet
No. 228.61 can be used all year round.
Depending on fuel quality (sulfur content), oil
change intervals must be shortened.
Oil change
!
If engine oils of different grades are mixed,
the engine oil change intervals are short-
ened compared with engine oils of the same
quality.
Therefore, only mix engine oils of different
grades in exceptional circumstances. Set
the sheet number of the engine oil of the
lower grade under
Engine oil grade
Engine oil grade
in
order to avoid damage to the engine.
!
If the SAE class (viscosity) of the engine oil
used is not suitable for continually low out-
side temperatures below -4 ‡ (-20 †) this
could cause engine damage.
The specified temperatures of the SAE class
always refer to freshly added oil. Engine oil
ages during driving due to soot and fuel resi-
due. This impairs the characteristics of the
engine oil, particularly at low outside tem-
peratures.
If the outside temperature is under -4 ‡
(-20 †), Mercedes-Benz strongly recom-
mends using engine oils of SAE class 5W-30
or 0W-30.
Use only all-season oils.
Oil change intervals are dependent on the fol-
lowing:
R
the operating conditions of the vehicle
R
the grade of the engine oil used
X
Select the SAE class of the engine oil in
accordance with outside temperatures.
Information on the SAE classes and outside
temperature ranges can be found in Sheet
No. 224.2 in the Mercedes-Benz Specifica-
tion for Service Products.
The maximum oil change interval can only be
achieved by using engine oils of particularly
high quality in accordance with Sheet No.
228.61 of the Mercedes-Benz Specifications
for Service Products. The on-board computer
automatically shows the date of the next oil
change.
Adding/refilling engine oil
!
If too much oil is added there is a danger
of damage to the catalytic converter or
engine. Have excess oil siphoned off.
When refilling, Daimler Trucks North America
recommends that you only use engine oil of
