Well, I just had my car's first oil/filter change performed this morning. At the same time, I had the oil switched to 5W20 'Mobil 1', which happens to be the only synthetic motor oil brand/viscosity that my particular 'Five Star' Chrysler dealer recommends for the 'LX platform' models. This works for me , as I was going to get the 'Mobil 1' all along anyway. Although the oil/filter change wasn't free, the car wash was.
