Lube oils are classified by DEUTZ into quality classes according to their performance capability. Oils according to other comparable specifications can be used.

The exact assignment of permissible oil quality and oil change intervals to the engines is listed in chapter 6.1.1.
In case of doubt, please ask your service representative.
*For oil change intervals see 6.1.1 For oil filling amounts see 9.1
Since lube oil changes its viscosity (viscidity) depending on temperature, the ambient temperature of the location of engine operation is decisive for the selection of viscosity class (SAE class). Refer to the oil viscosity diagram on the right to achieve optimal operating performance.
Falling below the temperature limits occasionally can impair the cold start ability, but will not lead to engine damages. In order to minimise wear, the operating limits should not be exceeded over a long period of time. Oil changes determined by the time of year can be avoided by using multi-viscosity oils. Multi-viscosityoils,inparticularsmoothrunning oils, also have the effect of reducing fuel consumption.
