Hey guys just bought my first saab today. Its a 2007 saab 9-3 turbo 2.0t and was wondering is there any issues known about these cars i should address before i run it real hard. I know it has a timing chain on it do these go bad ever and what about the oil i should run in it. It says mobil one synthietic but how much and what grade. Any help would be nice.
