My car has close to 2000 miles. I have followed the break-in as instructed in the user manual. At about 1500 miles my low warning light came on. I went into the dealer they checked it, my oil line was at the top of the lowest one third. The dealer put one quart in which brought it back to the bottom of the highest one third. All seemed okay, until on the way home my low warning light came on. I checked the dipstick and it again was at the lowest third. Again checked underneath the car to make sure that nothing seemed leaking, which it wasn't. Dealer said this wasn't abnormal as he said he expected it hadn't been fully topped off during PDI. He put one more full quart, 1/2 quart at a time and checked it after running the car for several minutes. After the second full quart it again was at the bottom of the upper third mark. I (understandably) have been keeping an eye on it, and today was surprised to find the oil level at the top of the bottom third mark. Putting in 1/2 quart at a time it took a full quart to bring it up to the expected upper third. So here I am close to 2000 miles having put a total three extra quarts into the car with no obvious source of leakage or consumption. This is much more than I ever saw in either of my M3s. I will give the dealer an call tomorrow, but I would appreciate any thoughts anyone has.
