Engine oil SAE classification
Viscosity indicates the flow characteristics of a
fluid. If an engine oil has a high viscosity, this
means that it is thick; a low viscosity means thatit is thin.
Depending on the respective outside tempera-
tures, select an engine oil according to SAE
classification (viscosity). The table displays the
SAE classification to be used. The low temper-
ature characteristics of engine oils can notice-
ably deteriorate during operation, e.g. from
aging, soot and fuel accretion. For this reason,
regular oil changes using an approved engine oil
from the suitable SAE classification are urgently
recommended.
Additives
!Do not use any additives in the engine oil.
This could damage the engine.
Miscibility of engine oils
!Mixing oils reduces the benefits of using
high grade engine oils.
We recommend that you only add engine oil of
the same quality grade and SAE class as used
when the engine oil was last changed.
If, in exceptional cases, oil of the type in the
engine is not available, top up using another
approved mineral or synthetic engine oil.
If the quality grade is not available for diesel
engines, you may also add engine oils meeting
the requirements in MB Sheet Number 228.5,
229.3 or 229.5. The quantity to be added is then
limited to a maximum of 1 qt (1 l).
Engine oils are differentiated according to:
Rengine oil brand
Rquality grade (sheet number)
RSAE class (viscosity) Subsequently have the engine oil changed at the
earliest possible opportunity.
Interval for oil change
The on-board computer automatically shows
the date for the next oil change as an event
message in the display.
Only by using engine oil with a particularly high
quality grade, e.g. according to Sheet Number
228.51 of the Mercedes-Benz Specifications for
Service Products, can the maximum interval for
oil change be achieved.
We recommend having the oil changed at a
qualified specialist workshop.

Capacities
!Do not add too much oil. adding too much
engine oil can result in damage to the engine
or to the catalytic converter. Have excess
engine oil siphoned off.

Information about oil consumption
!If the vehicle is predominantly used for
short-distance driving, this could lead to a
malfunction in the automatic cleaning func-
tion for the diesel particle filter. As a result,
fuel may accumulate in the engine oil and
cause engine failure.
Therefore, if you mainly drive short distances,
you should drive on a highway or on rural
roads for 20 minutes every 310 miles
(500 km). This ensures sufficient regenera-
tion of the diesel particle filter.
