Since specs can change from year to year with improvements in engine oil, it is best to check the Owners Manual for your particular car. A good all-season would be fully synthetic 0w40 or 5w40, for hot climates (always above 60F) 15w50.
In new Saabs, the manufacturer specifies Mobil 1 (synthetic). Several Saab repair shops also recommend Mobil 1 as it is good in minimizing the buildup of carbon and sludge. Do NOT use the extended oil change intervals that some synthetics claim.
To change oil in Saab 9-3 the hood will need to be opened and then the oil drained by using the drain pan. With the oil plug removed, the oil can now be changed.
