When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick,
add at least one quart/liter of the
recommended oil. This section
explains what kind of oil to use. For

.
Notice:
Do not add too much oil.
If the engine has so much oil that
the oil level gets above the
cross-hatched area that shows
the proper operating range, the
engine could be damaged.

for the location of the
engine oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when through.
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.
