• 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 −20°F
(−29°C), 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.
