Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don’t, the oil
dipstick might not show the actual level.
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
When to Add Engine Oil
If the oil is at or below the cross-hatched area at the tip
of the dipstick, then 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, see Capacities and Specifications
on page 5-100.
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.
See Engine Compartment
Overview on page 5-12 for
the location of the
engine oil fill cap.
Be sure to add enough oil to put the level somewhere
in the proper operating range in the cross-hatched
area. Push the dipstick all the way back in when you
are through.
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.
