Viscosity class:
The viscosity class has to be selected on the basis of the cold start temperature.
The following viscosity classes are permitted for the engines: 5W30, 5W40,
10W30, 10W40 and 15W40. The change intervals according to oil category must
be observed.
Difficulty factors
Difficulty factors can be:
– Frequent cold starts
– Environmental influences
•
Operating temperature
•
Dust
•
High humidity
•
Long standstill times
If there are difficulty factors or difficult usage conditions, the oil change and filter
change must be performed according to the following table.
Engine oil change intervals:
The change intervals are defined as follows:
Basic oil change interval
* Factor
oil category
* Factor
sulfur content
=
change
interval
The basic oil change interval is defined in the maintenance tables.
The factor “oil category”:
Factor “sulfur content”:
