Cold Temperature Operation
If you are in an area of extreme cold, where the
temperature falls below ?20F (?29C), 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 speci?cation, 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 you need for good performance
and engine protection.
Engine oil system ?ushes 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 lets you
know when to change the engine oil and ?lter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions,
the mileage at which an oil change will be indicated
can vary considerably. For the oil life system to
work properly, you must reset the system every time
the oil is changed.
When the system has calculated that oil life has
been diminished, it will indicate that an oil change is
necessary. A CHANGE OIL message will come on.
See DIC Warnings and Messages on page 3-38.
Change the oil as soon as possible within the next
600 miles (1 000 km). It is possible that, if you are
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 ?lter must
be changed at least once a year and at this time the
system must be reset. Your dealer/retailer has trained
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.
