Fleetguard, Mopar, or Cummins filter.... one in the same. When you see how your oil filter fits on that 14 you won't fill it prior to install. Even on my 01 I've never filled it. Interval.... follow the minder your truck is equipped with and it will take you anywhere from 10-14K interval. I'd say anywhere from 7-9 k would be fine if your not comfy with extending it. We run Rotella 15-40 in the reels at work.
