However, 1 month later(1000 miles) I noticed that about 0.4 qt was gone when doing oil level check. So I brought it back to another BMW dealer. They also said it's normal, and they are advised by BMW that they won't do diagnose unless the consumption is more than 1qt/750 miles. They also said that my car was almost new and that I shouldn't worry about anything as it will be covered by warranty. So, they added 0.4 qt and documented everything.
Since I planned to take the M340i to track, I decided to do an early oil change off CBS schedule. So I took the car back to dealer again. I also got the emission recall done at same time. Interesting thing was that the oil consumption issue seemed to stopped. The oil level was full even after I finish the track day.
So, I have no idea if it has something to do with the emission recall, or it has something to do with engine breaking in. I got my car back in May 2019, so it might be the early production, which BMW forgot to detune.

Read my post, dealer told me it's because of the break-in oil and that it should remedy itself after first oil change. Hopefully that's true, either way I will know soon enough. |
I don't think this car has special break-in oil as the M Power model. But changing oil seems to resolve my issue. Easiest thing to verify is to do oil analysis. My friends sent oil sample from his 1200 miles Supra(same B58 engine), and blackstone was able to identify that the car is in break in period.
So, I think in future I'd always do an early oil change, then do it based on CBS schedule. Or, if I track the car, maybe I'll do additional one between each CBS oil change.
