Engine oil

To check and refill engine oil
The engine oil used has a significant effect on the engine’s per-
formance, service life and startability. Be sure to use oil of the
recommended quality and
appropriate viscosity.
All engines consume a certain amount of oil during normal
operation, and engine oil consumption is greatly influenced by
payload, engine speed, etc. Ther efore, it is important to check
the oil level at regular intervals or before starting a long trip.
This check must be made with the engine warm but not run-
ning. Park the vehicle on a level surface, stop the engine, and
then wait a few moments to allow the engine oil in circulation
to return to the oil pan to ensure accurate measurement.
Remove the dipstick and wipe it with a clean cloth. Reinsert
the dipstick as far as it goes. Remove the dipstick and read the
oil level, which should always be within the range indicated.
If the oil level is below the specified limit, remove the cap
located on the cylinder head cover and add enough oil to raise
the level to within the specified range.
Be sure to use the specified e ngine oil and do not mix various
types of oil. Also, avoid mixing different makes of oil together
if possible.
After adding oil, cl ose the cap securely.
Use only the recommended oils with an MB classification as
specified in this manual.

Selection of engine oil
Petrol-powered vehicles
Except for vehicles with turbocharger
● Select engine oil of the proper SAE viscosity number
according to the atmosp heric temperature.
● Use engine oil conforming to the following classification:
• “MB 229.1” or higher
NOTE● Use of additives is not recommended since they may
reduce the effectiveness of ad ditives already in the engine
oil. It may result in failure of the mechanical assembly. Vehicles with turbocharger
● Select engine oil of the proper SAE viscosity number
according to the atmo spheric temperature.
● Use engine oil conforming to the following classification:
• ACEA classification: “For service A1/B1, A3/B3, A3/B4 or A5/B5”
• API classification: “For service SG” or higher

NOTE●Use of additives is not recommended since they may
reduce the effectiveness of additives already included in
the engine oil. It may result in failure of the mechanical
assembly.
● SAE 5W-30 engine oil can be used to improve engine
startability in very cold weather areas where the lowest
atmospheric temperature is below the range shown in the
illustration.
In this case, use engine o il conforming to the following
classification: • ACEA classification: “For service A3/B3, A3/B4 or A5/B5”
• API classification: “For service SG” or higher
