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 Speci®cations on page 5-101.
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 5-12for
the location of the
engine oil ®ll 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.
