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.
