What should be a normal oil temperature?

On my previous car (F30 320D) the oil temperature indicator always stayed stable at 90℃(194℉).

In my M2 LCI, the temperature is most of the time stable around 95℃(203℉) but a lot of times also around 110℃ (230℉) even when I'm just cruising on the highway at 120kmh (75mph) with an ambient temperature of 15℃ (59℉).

Is this normal? What temperatures do you guys see/notice?

Completely normal and completely fine.

i see between 95 and 108C even in 40+C temps

For N55 engine this temperature is normal.

Something you should know is the cooler works harder in Sport and Sport+ mode than Comfort, so the car gets up to temperature faster in Comfort and probably cruises at a higher temp as well.

This all means if you want to cool the turbo down after a drive idle the car in sport for a minute for faster cooling.

I did some logging last night with the Vlink OBD (used for Bimmercode) and Auto Doc Pro iOS app ($18). When in Sport or higher, coolant stayed at 165F and oil at 195F.

When I switched to Comfort, both elevated to 220F in about three minutes. Switched back to Sport and temps came down in 4-5 min.

Will do some logging the next time I’m on track in DSC off to see how high the temps get.

This is due in part to the oil to coolant heat exchanger.

The engine is more thermally efficient at a higher temp, with better VE and fuel efficiency. So, the new M- motors run hot in Comfort. Since temps rise significantly under more boost and higher throttle inputs, additional cooling (fan, etc) is provided to stabilize temps when on-track or spirited driving (i.e. in Sport/Sport +)

Nice design element, IMO

This is what it shows on mine most of the time and it never got to 120C. I have another post about Oil Temp to see at what temperature can I punch the car. I suppose by the time it reaches 95C we could punch it!
