4.1 Lubricating oil Consumables

z If the oil change intervals are not reached
within a year, the oil change should be car-
ried out at least 1x yearly.
Viscosity
The ambient temperature at the installation site
or area of application of the engine is decisive
for the choice of the right viscosity class. Too
high a viscosity can lead to starting difficulties,
too low a viscosity can endanger the lubricati-
on effect and cause high lubricating oil con-
sumption. At ambient temperatures below -40
°C the lubricating oil must be pre-heated (e.g.
by storing the vehicle or machine in a shed).
The viscosity is classified according to SAE.
Multipurpose oils should be used basically.
Single purpose oils can be used in closed, he-
ated rooms at temperatures >5 °C.
Depending on the ambient temperature we re-
commend the following common viscosity
classes:
