Saturn 2007 Vue Owner's Manual page 319

If the oil is below the MIN (minimum) mark for the
2.2L L4 engine or below the lower mark (B) for
the 3.5L V6 engine, you need to add at least
one quart/liter 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 414.
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.
2.2L L4 Engine
See Engine Compartment Overview on page 314
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.
