Saturn 2010 AURA Hybrid - Manual (Page 274)

When to Add Engine Oil
If the oil is below the MIN (minimum) mark, 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 6-92.
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 6-14
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.
