Saab 9-3 years 2001 2003 and prob others should ONLY run on fully synthentic oil. Theres a design problem that causes sludge and any other oils only contribute to the sludge.
5w-40 fully synthetic

The Saab 9-3 typically requires around 5.5 to 6 quarts (approximately 5.2 to 5.7 liters) of oil, depending on the engine type and model year. It's important to check the owner's manual for the specific engine variant to ensure the correct oil capacity. Always use the recommended oil type for optimal performance.
5.5 QTS.
5W-20 ( according to the 2001 Ford Mustang Owner Guide )
10w30 if using regular oil. I recommnd Spectro 10w30 clutch saver oil.
In most climates it takes 5W-30.
Depends on your climate. Consult the owners manual.
5 w 20 ( according to the owners manual )
