Saturn owners-what motor oil has worked the best for you? And what oil filters and air filters have worked the best? Personally myself, I have found that Mobil 1 10W-30, Chevron Supreme, and Schaeffer's motor oils have worked well in my car. I still am trying to decide what oil filter works best on a Saturn. I am going to use a Wix next, because I was able to buy one foe less than 5 bucks at a place that now sells Wix products. I am using a NAPA Gold air filter right now.
