According to the manual on my 2002 M, in liters, in states that you should put in 4.7 with filter change and 4.3 w/o. I buy the Mobil One 5w30 in four liter jugs when on sale plus a one liter bottle to make up five liters. Is this classified as a tad overfilled? In addition, Mobil One has now come up with a 4.4 liter jug. This confuses the issue since it would be short by .3 liters according to the manual. Ideas anyone?
