2007 Saab 9-7X Owner's Manual - Page 335

If the oil is below the cross-hatched area (L) for the 4.2L L6 engine or below the cross-hatched area at the tip of the dipstick for the 5.3L V8 engine, you will 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 445. 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 4.2L L6 engine or above the cross-hatched area for the 5.3L V8 engine, the engine could be damaged. See Engine Compartment Overview on page 330 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. 335
