3.13 Engine oil specification 

The engine oil quality has a significant influence on the lifetime, 

performance and thus also the cost-effectiveness of the engine. 

The ambient temperature at the installation location or application 

of the engine is crucial for the selection of the correct viscosity 

class. 

Too high viscosity can result in starting difficulties; too low viscosity 

can endanger the lubrication effect and result in high lubrication oil 

consumption. The viscosity is classified according to SAE. 

Basically, use mulltigrade oils. 

Depending on the lubrication oil temperature, we recommend the 

following common viscosity classes.
