SUBJECT:
USE OF BREAK-IN OIL AND BREAK-IN OIL FILTER AFTER MAJOR ENGINE REPAIRS ALL MODELS
The use of Mercedes-Benz approved break-in oil and a break-in oil filter (see Parts Information below) is mandatory for the first 800-1000 miles of
operation after major engine repairs. This will assure good oil control and normal oil consumption after the break-in period and avoid warranty conflicts
in case of premature failures after repairs.
The following repairs require the use of the break-in oil and filter:
1.. New engine replacement or exchange engine installation (break-in filter already with engine).
2.
Short block (fitted block) installation.
3.
Re-honing and piston ring replacement. (1)
4.
New crankcase installation.
5.
New piston installation. (1)
(1)
NOTE: In aluminum engines (i.e. M116.96/117.96), the use of break-in oil and filter is not required if only new pistons or rings are installed.
After the break-in period (800-1000 miles), normal service schedules must be resumed.
