There are a few threads on this. Most without any real solution.
What oil are you using? It should be 5W20 or 0W20. Switching to 0W20 may resolve this.
What oil filter are you using? If you are using FRAM, try Motorcraft, WIX, or Mobil1.

I would point you in the direction of "both my LS' have done this and I've talked to dealership (mine is still under warranty) and mechanics and nobody can find anything wrong / they all say it seems like normal operation (the dealer especially says that last part).
