What Kind of Engine Oil to Use
Look for two things:
•
GM6094M
Your vehicle’s engine requires oil meeting GM
Standard GM6094M. You should look for
and use only an oil that meets GM Standard
GM6094M.
•
SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is
best for your vehicle.
These numbers on an oil container show its
viscosity, or thickness. Do not use other
viscosity oils such as SAE 20W-50.
Oils meeting these
requirements should
also have the starburst
symbol on the
container. This symbol
indicates that the oil
has been certified by the
American Petroleum
Institute (API).
You should look for this information on the oil
container, and use only those oils that are identified
as meeting GM Standard GM6094M and have the
starburst symbol on the front of the oil container.
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 your warranty.
