CAUTION
Damage to the catalytic converter and/or particulate filter
from using unsuitable engine oil.
Unsuitable engine oil diminishes the functionality and service life
of the catalytic converter and/or particulate filter.
Only use engine oils with very low quantities of sulfate ash,
phosphor and sulfur – so-called "low SAPS" oils which fulfill at
least one of the specifications mentioned above.
Oil viscosity
24
Select the recommended viscosity depending on the ambient temperature at
which the engine will be operated.
CAUTION
