For a 11-12 year old car, it's not an unusual symptom. And it's nothing serious either.
Just make sure you use a good quality synthetic oil. For cold temperatures, I would recommend you to use the Castrol 0W-30 or Mobil 1 0W-40; and use good quality (unleaded 98) fuel.

sounds like the Vanos Valve System there's alot going on in the top end and as soon as it gets oil up there it stops this is most prevalent when its cold
