Quality and capacity of engine oil
%
The containersofthe various engine oils are
markedwiththe ACEA (Association of Euro‐
pean AutomotiveManufacturers) and/or API
(America PetroleumInstitute)classifications.
Onlyuse approved engine oils that corre‐
spond to theMBSpecificationsfor operating
fluids and theprescribed ACEA and/or API
classifications namedbelow.Engine oilsof
other grades arenot permissible and can
result in theloss of theNew Vehicle Limited
Warranty. The use of other engine oils not
approvedfor diesel engines can damagethe
diesel particulatefilter (DPF).

Viscosity of theengine oil

NOTE Engine damagedue to incorrect
SAEclassification (viscosity) of the
engine oil
If theSAE classification (viscosity) of the
engine oil added is notsuitable forprolonged
lowoutsidetemperatures, it maycause
engine damage.
The temperaturereadings of theSAE classifi‐
cation arealwaysbased on fresh oil. Engine
oil ages when driving as aresult of sootand
fuel residue. The characteristicsofengine oil
deterioratesignificantlyatlow outside tem‐
peratures.

Use an engine oil of theappropriateSAE
classification at lowoutsidetempera‐
tures.
#
Use oil forall-year-round operation.
The temperaturereadings of theSAE classifica‐
tion arealwaysbased on fresh oil. The tempera‐
turecharacteristics of theengine oil, especially at
lowoutside temperatures, can deterioratesignifi‐
cantly due to agingwhen driving.
Therefore, Mercedes-Benzrecommends that you
changethe engine oil beforethe startofthe cold
season. Onlyuse an approved engine oil in the
prescribed SAEclassification forthis purpose.
The viscosity indicates theflowcharacteristics of
afluid. With regard to engine oil, ahigh viscosity
is synonymous withthickliquid and alow viscos‐
ity withthin liquid. Depending on theoutside
temperatures, select theengine oil according to
theSAE classification (viscosity).The table shows
theSAE classifications to be used. The lowtem‐
peraturecharacteristics of engine oils can deteri‐
oratesignificantlyduring operation due to aging
and sootand fuel accretion, forexample. Aregu‐
lar oil changewithanapprovedengineoil in the
appropriateSAE classification is therefore
strongly recommended.
Additive

NOTE Engine damagedue to use of addi‐
tives in theengine oil
The use of additional additives in theengine
oil can damagethe engine.
#
Do notuse anyadditional additives in
theengine oil.
Miscibility of engine oil
The benefits of high-quality engine oils are
reduced by mixing oil.
We recommend that youonly use engine oil of
thesame grade and SAEclassification as theoil
filled at thelastoil change. If, in exceptional
