Changing the earl, just exploring underneath the car and getting to know it. Also rotated the tires since I had to plug one of the fronts and these cars have a little bit of positive camber in them so they were starting to wear unevenly. These damn things take EIGHT quarts of oil!! But now that I got whatever it is that the dealer put in it out, and Mobil 1 with an STP additive in it, it runs alot smoother/quieter.
