4.1.1 Quality Grade
The lube oil quality grade is defined by
specifications. The following lube oil
specifications are approved:
lube oil quality class:
classification/specification
DEUTZ- DQC I DQC II DQC III
ACEA- E2-96 E3-96/E5-02 E4-99
API- CF/CF-4 CG-4/CH-4 -
Worldwide
- DHD-1 -

4.1.2 Viscosity
Generally, multi-grade oils shall be used. In
closed heated rooms at temperatures >5°C,
also single-grade oils can be used. The
indicated lube oil grades must, of course, also
be observed for single-grade oils.
As the viscosity of lube oil is dependent on
temperature, the choice of SAE grade
should be governed by the ambient
temperature prevailing at the engine
operating site.
Optimum operating behaviour will be
attained if you take the accompanying oil
viscosity diagram as a guide.
Should the temperature fall temporarily
below the limits of the SAE grade selected,
cold starting may be affected but the engine
will not be damaged.
In order to keep wear to a minimum, do not
exceed application limits for extended
periods of time.
Oil changes dictated by the seasons can be
avoided by using multi-grade lube oils. Mul-
ti-grade oils - particularly low-friction oils -
also reduce fuel consumption.
