Warning:
Operation with biodiesel (fatty acid methyl ester) is
not permissible.
The quality of oil used has a massive influence on the service
life of a major assembly and you should therefore only use
operating fluids which comply with the Mercedes-Benz Speci-
fications for Operating Fluids.
The sulfur content of the fuel also has an effect on the ser-
vice life of the engine.
The sulfur content of the fuel can be set to three stages using
the on-board computer.
•
0 – 0.05 % sulfur content = factor 1
•
0.05 – 0.1 % sulfur content = factor 0.5
•
> 0.1 % sulfur content = factor 0.3
Roughly 2 weeks before a service is due, the driver is infor-
med about this via a pop-up message when the ignition is
switched on. The next warning stage appears with the mes-
sage "Service immediately". All of the displayed messages are
stored in the memory so that, in the event of complaints, it is
possible to determine when each message was displayed.
Engine oil
Engines 934.9 and 936.9 may only be operated with engine
oil in accordance with sheet 228.51 (Low SPAsh multigrade
service engine oils) of the Mercedes-Benz Specifications for
Operating Fluids.
