What Kind of Engine Oil to Use
Look for two things:
•
GM6094M
Your vehicle’s engine requires oil meeting GM
Standard GM6094M. 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).
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.
