Just returned from my dealer. I asked them to order in Mobil 1 0-40 for an oil change. I was told Chrysler no longer deals with Mobil and uses Penzoil 5-40. The head parts guy told me this change occurred some time around the bankrupty and he did not know if it had to do with that or it just happened around the same time. I figure for the 2000 or so miles I put on the car before I put it away for the winter I can live with the 5-40 and do my semi annual winter storage change with Mobil 1 0-40. So much for dealing with Chrysler.
