SERVICE AND MAINTENANCE
6.1 Lubrication System
6.1.1 Oil Change Intervals
The oil change intervals are
dependent on the engine application
and the quality of the lube oil.
If the engine runs fewer hours during
the year than stated in the table, the
oil should be changed at least once
a year.
The table refers to the following
conditions:
- For diesel fuel: sulphur content max.
0.5% by weight.
- Continuous ambient temperatures
down to -10°C (+14°F)
If the sulphur content is > 0.5 to 1% or
the continuous ambient temperature
below -10°C (+14°F), the intervals
between oil changes should be
halved.
In case of fuels containing more than
1% sulphur, contact your service
representative.
