As a BMW tech once told me, these cars burn oil like they burn gasoline. Very normal and not limited just to BMWs...I've put about 2500 miles on my Pana and added a quart of 0W40 to the engine last weekend. My advice: research the recommended oil for your vehicle then go to Amazon.com and purchase a case to keep in your garage.
