When to Add Engine Oil
If the oil is at or below the L mark for the L6 engine or
the cross-hatched area at the tip of the dipstick for
the V8 engine, 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 5-109.
Notice: Do not add too much oil. If your engine
has so much oil that the oil level gets above
the F mark that shows the proper operating range
for the L6 engine or above the cross-hatched
area for the V8 engine, 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. 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.
