In my '04 LJ - Previous owner had oil changed at 89500 miles at a Jeep Dealer and they used 10w30 Mopar with M-090 Mopar filter. Engine was perfectly quiet on cold start. I changed oil at 92500 with Penzoil High Mileage CONVENTIONAL 10w30 and Mopar M-090 filter. No noise after immediately starting to move out of garage, and no noise the second morning I started it. This morning - lifters tapping for about 2-3 minutes before quieting down! Anyone else have this sort of experience?
