I'm just trying to gather some information from fellow saturn owners. I have a 98SC2, its about to roll past 70k and at 70,100mi I'll be done with the first step of my Auto-rx treatment. When that is complete I intended on running mobil 1 10w30 in 7,500mi intervals with a high quality filter (havent decided on a specific one yet) But before I invest any more time I would like to hear from some of you who are running the same engines. (1.9l DOHC) What oil are you using? why? What filter? why? How many miles are you up too on the car? how has it been holding up for you? I'm at 70k now, and for alot of american cars 70k is at or past mid-life (or so it "seems") . I hear saturn is a bit different (hopefully) I'm curious to know what to expect! I want this car to go for a long, LONG, LOOONNNGGGG time!
