Eng ine oil
Engine oil is identified b y its grade and
viscosity. When choosing which engine oil
to use, g ra de is more important than

The new eng ine oil GM-Dexos 2 is of the
highest quality available at the moment. If
it is una vailable, engine oils of other listed
qualities have to be used.

Oil from different manufacturers and of
different brands can be mixed prov iding

(g ra de a nd viscosity).
Not ev ery engine oil a vailable on the
market satisfies the q uality requirem ents,
so alwa ys check whether the required
specifications and c lassifications are
written on the container.
If an engine oil of the required grad e is not
available, a m aximum of 1 litre of ACEA
A3/B4 or A3/B3 grade may be used (only
once between eac h oil cha nge). The
viscosity should be of the correct rating.

Engine oil visc osity
Only use eng ine oils of viscosity 0W-30,
0W-40, 5W-30 or 5W-40.
The SAE v iscosity classification defines the
fluidity of the oil: the oil is more viscous
when cold than when hot.
Multigrade oil is indicated by two num bers.
The first number followed by a W gives the
viscosity at low temperature and the
second number gives the viscosity at high
temperature.
