Vehicle Care 9-13
.GM6094M
Use only an oil that meets GM
Standard GM6094M.
.SAE 5W-30
SAE 5W-30 is best for the
vehicle. These numbers on an
oil container show its viscosity,
or thickness. Do not use other
viscosity oils such as
SAE 20W-50.
.American Petroleum Institute
(API) starburst symbol
Oils meeting these requirements
should have the starburst
symbol on the container. This
symbol indicates that the oil has
been certified by the American
Petroleum Institute (API).Notice:
Use only engine oil
identified as meeting GM
Standard GM6094M and showing
the American Petroleum Institute
Certified For Gasoline Engines
starburst symbol. Failure to use
the recommended oil can result
in engine damage not covered by
the vehicle warranty.
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.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.
