Additives
!
Do not use any additives in the engine oil.
This could damage the engine.
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.
Oil change
Oil change intervals depend on the vehicle's
operating conditions and the quality of the
engine oil used. The on-board computer auto-
matically shows the date for the next oil change
as an event message in the display.
Mercedes-Benz recommends having the oil
changed at a qualified specialist workshop.
Information about oil consumption
Depending on the driving style, the vehicle con-
sumes a maximum of 1.0 US qt (1.0 l) of engine
oil over a distance of 620 miles (1,000 km).
Oil consumption may be higher if:
R
The vehicle is new.
R
You mainly operate the vehicle under arduous
operating conditions.
R
You frequently drive at high engine speeds.
Regular maintenance is one of the preconditions
for moderate rates of consumption.
You can only estimate the oil consumption after
you have driven a considerable distance.
Check the engine oil level on a regular basis, e.g.
weekly or each time you refuel (
