GM recommends Mobil 1
oils that show the dexos approved
logo for its dry sump equipped
engines.
Use of Substitute Engine Oils if
dexos2 is unavailable: In the event
that dexos2-approved engine oil is
not available at an oil change or for
maintaining proper oil level, you
may use substitute engine oil that
meets ACEA C3 of the appropriate
viscosity grade.
Caution
Use only engine oil that is
approved to the dexos2
specification or equivalent engine
oil as defined in the preceding

paragraph. Failure to use the
recommended engine oil can
result in engine damage not
covered by the vehicle warranty.
Viscosity Grade
Use SAE 5W-30 viscosity grade
engine oil.
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below 29°C
( 20°F), an SAE 0W-30 oil may be
used. An oil of this viscosity grade
will provide easier cold starting for
the engine at extremely low
temperatures. When selecting an oil
of the appropriate viscosity grade,
always select an oil of the correct
specification. See Specification
earlier in this section for more
information.
For track events or competitive
driving, use Mobil 1
(Continued)
engine oil. An instrument cluster
warning light will be illuminated at
high oil temperatures. See Driver
Information Centre (DIC) on
page 5-25.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils meeting the
dexos2 specification are all that is
needed for good performance and
engine protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
