Saturn 2008 Aura - Manual (Page 269)

If the oil is below the cross-hatched area at the tip of the
dipstick, 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 5-104.
Notice: Do not add too much oil. If the engine
has so much oil that the oil level gets above the
upper mark that shows the proper operating range,
the engine could be damaged.
See Engine Compartment
Overview on page 5-14
for the location of the
engine oil fill cap.
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.
