Engine Oil Viscosity
The following engine oils can be used:
A = single-grade oils
B = multigrade oils
C = easy run oils
depending on the outside temperature.
Engine Oil Quality
It is important that the following API and CCMC classes are
used:
Engines
Single and multigrade oils
Easy run oils
Petrol
API-SF/CC, SF/CD, SG/CC,
SG/CD, CCMC/G4
API-SF/CC, SF/CD, SG/CD
CCMC-G5/PD2
Important!
CD engine oils designed by manufacturers specially for diesel
engines are not suitable for petrol engines, unless a sufficient
performance class for petrol engines (e.g. API-SF/CCMC-G4)
is also indicated.
Disposal.
Observe the relevant national regulations when disposing of
used oil.
