Engine Oil
Engine Oil is identified by its Quality
and its Viscosity Grade. "Quality"
and "Specification" are equivalent
terms in this respect. Engine Oil
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 aging control,
whereas Viscosity Grade gives
information on the oil's thickness
over a temperature range.

Selecting the right Engine Oil
Selecting the right Engine Oil
depends on the proper Oil
Specification and SAE Viscosity
Grade.
Use and ask for Engine Oils with the
dexos™ Certification Logo. Oils
meeting the requirements of your
vehicle should have the dexos™
Certification Logo on the container.
This Logo indicates that the oil has
been approved by GM to the
dexos™ Specification.
Your vehicle's Engine was filled at
the factory with dexos™ approved
Engine Oil.
Use only Engine Oil that is approved
to the dexos™ Specification or an
equivalent Engine Oil of the
2398375
appropriate Viscosity Grade.
If you are unsure whether your oil is
approved to the dexos™
Specification, ask your service
provider.
