The new engine oil quality
Dexos 2 TM is the newest oil quality
and combines gasoline and diesel
performance. If it is unavailable,
engine oils of other listed qualities
have to be used.
Engine oil quality for European
service schedules
= All petrol and diesel

Alternative qualities if Dexos 2
not available:
GM-LL-A-025 = Petrol engines
GM-LL-B-025 = Diesel engines

service schedules
= All petrol and diesel

Alternative qualities if Dexos 2
not available:
GM-LL-A-025 = Petrol engines
GM-LL-B-025 = Diesel engines
Alternative qualities if GM-LL-A-025
or GM-LL-B-025 are not available:
ACEA-A3/B3 or
A3/B4
ACEA-A3/B4
ACEA-C3
Topping up engine oil
Engine oils of different manufacturers
and brands can be mixed as long as
they comply with the required engine

oil quality and viscosity.
If engine oil of the required quality is
not available, a maximum of 1 litre of
ACEA C3 grade may be used (only
once between each oil change). The
viscosity should be of one of the
below listed viscosity grades.
Use of engine oil with only ACEA A1/
B1 or only A5/B5 quality is explicitly

prohibited, since it can cause long-
term engine damage under certain
operating conditions.
Service and maintenance
Additional engine oil additives
The use of additional engine oil
additives could cause damage and

The SAE viscosity grade gives
with DPF
information of the thickness of the oil.
Multigrade oil is indicated by two
figures. The first figure, followed by
a W, indicates the low temperature
viscosity and the second figure the
high temperature viscosity. Please
select the approriate viscosity grade
depending on your minimum ambient
temperature.

Coolant and antifreeze
Use only silicate-free long life coolant
(LLC) antifreeze.
