I am familiar with all stories of how the n63 engines are burning oil, my wife has an f15 50i and never got the dreaded warning on the idrive display and neither have I. Last time I measured the level in mine was a couple months ago and was between min and max.
Today I run another measurement just to see how much it had dropped since the last check and i get the dreaded message to add 2qt of oil.
Now, I'm really concerned that the car was low on oil for days, weeks or even more because it never gave me the warning on its own.
Moreover, now I'm leery to do my own oil changes if the engine was wearing badly during this entire time.

Any suggestions?


Luckily always carry 2qts in the trunk so I'm good for today but this is really worrisome.
