Engine oils
Notes on engine oils
! Engine oils other than those of the quality
specified in this Operator's Manual are not
permitted.
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 tech-
nical standard.
For BlueTec
®
6 vehicles, only use engine oils
which correspond to Mercedes-Benz Specifica-
tions for Service Products, Sheet No. 228.51 or
228.31.
For BlueTec
® 6 vehicles with Fuel Efficiency
Package (FE1), use engine oils according to
Sheet No. 228.61, 228.51 or 228.31.
For all other vehicles, you can use engine oils
according to Sheet No. 228.5, 228.51, 228.3 or
228.31. Use the preferred engine oils according
to Sheet No. 228.5 or 228.3.
Engine oils according to Sheet No. 228.51 have
a higher quality standard and have a favourable
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. 228.51, and the viscos-
ity, e.g. SAE class 5W-30, on the oil container.
Scope of use
Multi-grade engine oils that comply with Sheet
No. 228.51 or 228.31 can be used all year
round.
Depending on fuel quality (sulphur content or
fatty acid methyl ester FAME), oil change inter-
vals must be shortened.
Oil change
! If you mix engine oils with differing oil
grades, the change interval for the engine oil
is reduced in comparison to mixtures of
engine oil of identical grade.
Therefore, only mix engine oils of differing
grade in exceptional circumstances. To pre-
vent damage to the engine, set the sheet
number of the engine oil with the lower grade
under
Engine oil grade
.
! If the SAE class (viscosity) of the engine oil
used is not suitable for continually low outside
temperatures below -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 temper-
atures.
If the outside temperature is under -20 †,
Mercedes-Benz strongly recommends using
engine oils of SAE class 5W-30 or 0W-30.
Use only all-season oils.
H
Environmental note
If you operate your vehicle using FAME fatty
acid methyl ester fuel (bio-diesel), special pre-
cautions must be taken and national specifi-
cations complied with when disposing of
engine oils. Information is available from any
Mercedes-Benz Service Centre.
Oil change intervals are dependent on the fol-
lowing:
R
the operating conditions of the vehicle
R
the grade of the engine oil used
R
the fuel type, e.g. FAME fatty acid methyl
ester fuel
X
Select the SAE viscosity class of the engine oil
to suit the 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.
