Service life of the lubricants
Note
In case of ambient conditions deviating from normal conditions, e.g. high ambient
temperatures, high relative humidity, aggressive ambient media, the intervals between
changes should be shorter. In such cases, contact Technical Support for assistance in
determining the individual lubricant change interval.
Note
Oil sump temperatures above +80 °C can reduce service life. A temperature increase
by 10 K halves the service life by the amount as shown in the figure titled "Guide values for
oil change intervals".
For a +80 °C oil sump temperature, the following service life can be expected when
observing the properties specified by Siemens AG:
