Please bear the following in mind
The engine oils are matched to the performance of Mercedes-Benz engines and service intervals. You should therefore only use engine oils and oil filters that are approved for vehicles with maintenance systems.
For a list of approved engine oils and oil filters, consult an authorized Mercedes-Benz Center or go to the Internet site http://www.mbusa.com (USA only).
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
intervals than those prescribed. You could
otherwise 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.
The table shows which engine oils have been approved for your vehicle.

MB Approval is indicated on the oil
containers.
Additives
Do not use any additives in the engine oil.
This could damage the engine.
