of another quality is not permitted and may
invalidate the New Vehicle Limited Warranty.
The use of other, non-approved engine oils fordiesel engines can cause damage to the die-
sel particle filter (DPF).
Use only engine oils that have been approved for
your vehicle according to the MB Specifications
for Service Products.

Multi-grade engine oils of the prescribed SAE
class (viscosity) may be used all year round, tak-
ing the outside temperatures into account.
Engine oil viscosity
!If the SAE viscosity class of the engine oil
used does not cover the outside temperature
range in which you are operating the vehicle,
it must be changed in good time, in particular
before the cold season commences. Using an
engine oil that does not have adequate tem-
perature characteristics can lead to engine
damage.
The temperature range information of the SAE
classification always refers to that of fresh oil.
The temperature characteristics of the engine
oil may deteriorate significantly due to aging
in use, especially at low outside tempera-
tures.
We recommend that you change the engine
oil before the cold season commences. Use
an approved engine oil of the specified SAE
class.
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 that it 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).
