Engine oils according to Sheet No. 228.51 are
high quality engine oils which have a positive
effect on the following factors:
R
the oil change interval length
R
engine wear
R
fuel consumption
R
the exhaust gas emissions
%
The quality grade is listed on the oil canister,
e.g. Sheet No. 228.51, and the viscosity, e.g.
SAE classification 5W‑30.
Application areas
You can use multigrade engine oils according to
Sheet No. 228.51 or 228.31 all year round.
The oil change intervals are shortened depending
on the fuel grade (sulphur content).
Oil change
*
NOTE Damage to the engine caused by
mixing engine oils
Mixing engine oils of differing qualities can
lead to shortened change intervals.
This can lead to engine damage.
#
Only use engine oils of differing quali‐
ties in exceptional cases.
#
In order to prevent engine damage, set
the Sheet Number of the engine oil with
a lower quality in the
Engine
Oil grade
menu.
*
NOTE Engine damage due to using
engine oil with inadequate temperature
characteristics
The engine oil used does not have adequate
temperature characteristics.
This can lead to engine damage.
#
Select the SAE classification (viscosity)
of the engine oil, depending on the sea‐
son and the average outside tempera‐
ture.
#
If the SAE classification of the engine oil
is not suitable for the outside tempera‐
ture: change the engine oil, in particular
before the cold season commences.
Oil change intervals depend on the following fac‐
tors:
R
vehicle operating conditions
R
quality of the engine oil used
R
the fuel type
Select the SAE classification (viscosity) of the
engine oil according to the outside temperature.
Information on the SAE classifications and the
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 is only achieved
with engine oils of a particularly high quality
grade, according to Sheet No. 228.51 of the
Mercedes-Benz Specification for Service Prod‐
ucts. The on-board computer automatically dis‐
plays when the next oil change is due.
Filling or topping up engine oil
*
NOTE Damage caused by topping up too
much engine oil
Too much engine oil can damage the engine
or the catalytic converter.
#
Have excess engine oil removed at a
qualified specialist workshop.
When you top up, Mercedes-Benz recommends
that you only use engine oil of the same quality
grade and SAE classification as the oil added at
the last oil change.
Check the oil level on the on-board computer
before topping up engine oil (

page 326).
Miscibility of engine oils
If you mix engine oils, you reduce the advantages
of high-quality engine oils.
Engine oils are differentiated according to the fol‐
lowing points:
R
engine oil brand
R
quality grade (Sheet No.)
R
SAE classification (viscosity)
If, in exceptional cases, engine oil of the type in
the engine is not available, top up using another
engine oil approved for Mercedes-Benz.
