Recommended fluids and
lubricants
Only use products that meet the
recommended specifications.
Damage resulting from the use of
products not in line with these
specifications will not be covered by
the warranty.
9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The
oil quality ensures e.g. engine
cleanliness, wear protection and oil
ageing control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Dexos is the newest engine oil quality
that provides optimum protection for
gasoline and diesel engines. If it is
unavailable, engine oils of other listed
qualities have to be used.
Recommendations for gasoline
engines are also valid for
Compressed Natural Gas (CNG)
fuelled engines.
Engine oil quality
dexos 2 = All petrol and diesel
engines
Alternative qualities if dexos is not
available:
GM-LL-A-025 = Petrol engines
GM-LL-B-025 = Diesel engines
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.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity
Use only engine oil viscosity grades
SAE 5W-30 (diesel engines) or
5W-40 (petrol, CNG engines).
The SAE viscosity grade 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 the low temperature
viscosity and the second figure the
high temperature viscosity.
Coolant and antifreeze
Use only antifreeze approved for the
vehicle, consult a workshop.
