When to Add Engine Oil
If the oil is below the cross-hatched area at the tip of
the dipstick, you will need to add at least one quart of oil.
But you must use the right kind. This section explains
what kind of oil to use. For engine oil crankcase
capacity, seeCapacities and Speci cations on
page 5-99.
See “Racing or Other Competitive Driving” under
Starting Your Engine on page 2-21for additional
information on engine oil.
Notice:Do not add too much oil. If your engine has
so much oil that the oil level gets above the
cross-hatched area that shows the proper operating
range, your engine could be damaged.SeeEngine Compartment
Overview on page 5-12for
the location of the
engine oil fill cap.
Be sure to add enough oil to put the level somewhere in
the proper operating range. Push the dipstick all the
way back in when you are through.
What Kind of Engine Oil to Use
Look for two things:
•GM4718M
Your vehicle’s engine requires a special oil meeting
GM Standard GM4718M. Oils meeting this
standard may be identified as synthetic. However,
not allsyntheticoils will meet this GM standard.
You should look for and use only an oil that meets
GM Standard GM4718M.
Notice:If you use oils that do not have the
GM4718M Standard designation, you can cause
engine damage not covered by your warranty.
