oil level drop?
When I first got the car in 1/2018 with 53k mi, the oil had been changed and the oil level read near MAX. After another 4k mi and 7 months of very spirited driving, the oil level now reads middle of the range but still says OK. Is this normal? Is it just a sensor issue or am I leaking a little? Have not gotten the "Add 1 qt." warning yet. I really dislike this electronic dipstick crap. I plan on changing my oil at 60k and then following the 5k mi oil change rule from there.
EDIT: I realize this is common for n54/n55, but my car is a 128 and has the n51. Hoped oil consumption wouldn't be an issue with this motor. Vehicle doesn't smoke at all, but I am having a longer warm start (almost like it is struggling to crank for about half a second, only when hot outside), but that has happened since I've had it.

This is an age-old subject, most cars don't go through much oil but it will be considered "typical" by a manufacturer to use up to a quart per 1000 miles. Aggressive driving would make that a touch more likely as well. Unless you know of an issue (i.e. smoky idle or acceleration) I'd probably just keep an eye on it.

I just had to put a quart in 5000 miles after my last oil change. 2nd or 3rd time I've had to do that.

I have a 2013 that read oil level minimum after ~2000 miles, added a quart and it showed oil level max. Since its the first few months of ownership, I'll blame it on my spirited driving. The level is back in the middle now after another ~1000 miles.
Sounds like mine is dropping faster than yours... I don't see any oil under my car or smoke . I can live with a quart every few k. |

I had an oil sensor go bad. Kept telling me I was middle, then low. I'd add some and then a while later it was middle or low.
Check for leaks on the lower engine tray. Look for leaks around the OFHG.

Yes, although you have the turbo motor. Mine is the 128i, and I hoped oil consumption wouldn't be as much of an issue.

I have heard OFGH being a common issue. Does it affect N51 too?

I don't have iDrive so no "green range" just a bar with min and max on it in my gauge cluster.

Will definitely check. Is it DIY? I would love to just take care of it myself

Will definitely check sensor. Wouldn't it say INACTIVE when checking the oil if it was bad? I know when my RDC got soaked it said TPMS was INACTIVE

The difference between the min and max marks is 1 quart. So if you drop from the max to the mid, you are down a pint.
As has been stated, a pint in 4K miles is not unusual and no cause for alarm. My wife doesn't keep track of when I add for her but she needs a quart or two between oil changes in her n52. I change mine more often and never have to add. A pint in 4K miles is just a quart in 8K which is not bad.
