Oil Consumption
If you receive customer reports in the above model AMG vehicles of excessive oil consumption due to repeated oil level messages in the instrument
cluster, review the information below and follow instructions accordingly.
Factors which may influence oil consumption:
1. Usage related influences that increase oil consumption:
^
The load spectrum is significantly higher than on comparable standard production engines
^
Driving profile (aggressive driving style)
^
Normal engine wear after break in is completed
2. Design related influences that increase oil consumption:
Engine 156
^
High RPM design
^
Large piston diameter
^
Low friction design
Engines 112.96x, 113.98x/99x, 275.98x:
^
Increased stroke (113.98x/99x) compared to the standard engine
^
Low friction design
^
Number of cylinders (275.98x)
^
Turbocharging (275.98x)
Before repair actions are taken, please note the following:
1. Oil consumption may be higher if the vehicle is new or frequently driven at high engine speeds.
2. An oil consumption measuring test should only be performed after the engine break-in period of at least 6200 miles (~10000 km).
