This is listed in your owner's manual, and somtimes on the oil fill cap. Call a dealer to make sure. 5W-30. It is listed in the owner's manual. The 3.8L V-6 uses 10W-30. Make sure you use the 5W-30 to allow for closer tolerances on the 3.4L, especially in colder weather. I would run 5w30 until you hit about 50,000 miles then switch to 10w30 as wear becomes more prevelent.
