...it to last? I bouht a 2003 chrysler sebring 2.7l with 49,552 miles on it. It runs great. It now has 55,007 miles. Up until 54,500 miles I had 2 oil changes with Conventional Pennzoil with 5W-30 and one quart of Rislone. I now use Mobil One 5W-30 Extended Performance and want to use 4k mile change intervals, how long can I expect this engine to last, looking through the oil cap recently, I have had sludge buildup on the cap, and the oil got dirty within 2 weeks. Is this a good sign or bad sign?
