When to Add Engine Oil

L6 Engine
V8 Engine
If the oil is below the L mark for the L6 engine or
the cross-hatched area at the tip of the dipstick for
the V8 engine, add at least one quart/liter of the
recommended oil. This section explains what kind
of oil to use. For engine oil crankcase capacity, see
Capacities and Specifications on page 5-120.
5-16
Notice: Do not add too much oil. If the engine
has so much oil that the oil level gets above the
cross-hatched area (F) that shows the proper
operating range for the L6 engine or above the
cross-hatched area for the V8 engine, the engine
could be damaged.
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.
See Engine Compartment
Overview on page 5-12 for
the location of the
engine oil fill cap.
