Lubricating oil change intervals
z
The intervals depend on:
lubricating oil quality
sulphur content in the fuel
type of application of engine
z
The lubricating oil change interval must be
halved if at least one of the following conditions
applies:
Constant ambient temperature below -10 °C
(14 °F) or lube oil temperature below 60 °C
(84 °F).
Sulphur content in the diesel fuel of 0.5-1 %.
In case of fuels containing more than 1% sul-
phur, contact your corresponding DEUTZ
partner.
operation with bio-diesel fuel
z
If the lubricating oil change intervals are not
reached within a year, the oil should be changed
at least once a year.

Viscosity
The ambient temperature at the installation site or in
the application area of the engine is decisive for
choosing the right viscosity class. Too high a viscos-
ity can lead to starting difficulties, too low a viscosity
can endanger the lubrication effect and cause a high
lubricating oil consumption. At ambient temperatures
below -40 °C, the lubricating oil must be pre-heated
(e.g. by storing the vehicle or the machine in a hall).
The viscosity is classified according to SAE. Multi-
purpose lubricating oils should be used basically.
Single-purpose lubricating oils can also be used in
enclosed, heated spaces at temperatures >5 ° C.
Depending on the ambient temperature we recom-
mend the following common viscosity classes:
The prescribed lubricating oil quality must
be observed when selecting the viscosity
class!
