Engine oil quality for European
service schedules
GM-LL-
A-025 = Petrol engines
GM-LL-
B-025 = Diesel engines
without DPF
ACEA-C3 = Diesel engines with DPF
GM = General Motors Europe
LL = Longlife
A or B = Engine oil quality specification
025 = Validity index
Opel engine oil meets classifications
GM-LL-A-025 and GM-LL-B-025 and
is therefore suitable for both petrol
and diesel engines.
Engine oil quality for international
service schedules
ACEA-A3 = Petrol engines
ACEA-B4 = Diesel engines without diesel particle filter
ACEA-C3 = Diesel engines with diesel particle filter These oil qualities must only be used
with the international service
schedule.
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 A3/B4 or A3/B3 grade may be
used (only once between each oil
change). The viscosity should be of
the correct rating.
Use of ACEA A1/B1 and A5/B5
engine oil is expressly forbidden,
since they can cause long-term
engine damage under certain
operating conditions.
Engine oil additives
The use of engine oil additives could
cause damage and invalidate the
warranty.
Engine oil viscosity
Use only engine oil viscosities SAE
0W-30, 0W-40, 5W-30 or 5W-40. The SAE viscosity rating defines the
ability of an oil to flow. When cold, oil
is more viscous than when hot.
Multigrade oil is indicated by two
figures. The first figure, followed by
a W, indicates low temperature
viscosity and the second figure the
high temperature viscosity.
Coolant and antifreeze
Use
only silicate-free long life coolant
(LLC) antifreeze.
The system is factory filled with
coolant designed for frost protection
down to approx. -28 °C. This
concentration should be maintained
all year-round.
Coolant additives intended to give
additional corrosion protection or seal
against minor leaks can cause
function problems. Liability for
consequences resulting from the use
of coolant additives will be rejected.
Brake and clutch fluid
Only use DOT4 brake fluid.
