I bought a 330CI three months ago. 53,000 miles. Car is in great shape. This morning I was setting out on a trip and the oil pressure light went on. Returned home, checked the oil, and it was a little below the minimum. Two questions. One, I am guessing that if I add oil, things will be okay. Second, should I expect this particular engine to burn some oil, and if so, how often should one check oil between recommended 15,000 mile oil changes? (The monitor on the dash indicated that I had 9,000 miles to go before an oil change, although it had been a year since the previous owner had changed the oil.) Thanks. This is a great site that offers a lot of help to a lot of BMW owners.
