^^Of all the oil threads I have read on here, I have avoided it because most people are experiencing about 1 quart per 3000 miles of consumption with Mobil 1.
My wife's 2007 BMW 328i is at about 70k miles right now and as long as I have known her (since about 35k miles) it has always consumed some oil as she always gets an oil light around 7500 miles into her 15000 mile factory specified OCI, and always changes the oil rather than just adding some. But until the last oil change, I had never worked on the car or payed any attention to the oil that she was having the shops put in it. So I put Castrol Edge 5W30 in and we will see if we get the same consumption, reduced consumption or, hopefully, none. If my inklings are correct, we should get minimal to none. :fingerscrossed:
