Cold Temperature Operation
If in an area of extreme cold, where
the temperature falls below
−
29°C
(
−
20°F), use either an SAE 5W-30
synthetic oil or an SAE 0W-30
engine oil. Both provide easier cold
starting for the engine at extremely
low temperatures. Always use
an oil that meets the required
specification, GM6094M. See
“
What
Kind of Engine Oil to Use
”
for more
information.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils with the starburst
symbol that meet GM Standard
GM6094M 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.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based
on engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably. For
the oil life system to work properly,
the system must be reset every time
the oil is changed.
On some vehicles, when the system
has calculated that oil life has been
diminished, a CHANGE ENGINE
OIL SOON message comes on to
indicate that an oil change is
necessary. See
Engine Oil
Messages on page 5

. Change
the oil as soon as possible within
the next 1 000 km (600 miles). It is
possible that, if driving under the
best conditions, the oil life system
might not indicate that an oil change
is necessary for over a year.
However, the engine oil and filter
must be changed at least once a
year and at this time the system
must be reset. For vehicles without
the CHANGE ENGINE OIL SOON
message, an oil change is
needed when the OIL LIFE
REMAINING percentage is near
0%. Your dealer has trained service
people who will perform this work
using genuine parts and reset the
system. It is also important to check
the oil regularly and keep it at the
proper level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 miles)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
