I guess it's possible that even in a couple of thousand miles of driving that I haven't exactly met those parameters... especially the idle for 5 minutes before shutoff. I've got an oil change coming up and will have it at the dealer. Will see if I can get an audience with a tech. Yes... I get oil changes at the Jeep dealer. They're 3 for $100 and since I have an extended warranty, I want record they were done. Plus... when they come back and say, "Oh... this is broken," I just remind them about the warranty and the "this" gets fixed!
