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.
