Vehicle Care 10-9
What Kind of Engine Oil to Use
Look for three things:
. 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
standards 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.
