Engine oil
General notes
!
Never use engine oil or an oil filter of a
specification other than is necessary to
fulfill the prescribed service intervals.
Do not change the engine oil or oil filter in
order to achieve longer replacement inter-
vals than those prescribed. You could oth-
erwise cause engine damage or damage to
the exhaust gas aftertreatment.
Follow the instructions in the service
interval display regarding the oil change.
Otherwise, you may damage the engine and
the exhaust gas aftertreatment.
When handling engine oil, observe the impor-
tant safety notes on service products
(
Y
page 199).
The engine oils are matched to the perform-
ance of smart engines and service intervals.
You should therefore only use engine oils and
oil filters that are approved for vehicles
with maintenance systems.
Consult a smart center to view a list of
approved engine oils and filters. Or visit the
website http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle.
Model

MB approval is indicated on the oil con-
tainers.

Additives
!
Do not use any additives in the engine oil.
This could damage the engine.
Engine oil viscosity
Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscos-
ity, this means that it is thick; a low viscos-
ity means that it is thin.
Select an engine oil with an SAE (viscosity)
classification suitable for the prevailing
outside temperatures. The table shows you
which SAE classifications are to be used. The
low-temperature properties of engine oils
can be significantly impaired during oper-
ation due to, for example, aging or soot and
fuel accretion. It is therefore strongly rec-
ommended that you carry out regular oil
changes using an approved engine oil with
the appropriate SAE classification.
