On my 2021 Mazda6, I took a video of the low oil warning, then selected the maintenance interval screen to show it was 2500 miles from the next oil change.
Valve stem steals were leaking so it wouldn't pass california smog
I got a ‘21 CX-9 and found out this model has a valve stem seal issue which causes the vehicle to burn oil around 4K after the oil change. Mazda has service bulletin out for this but I have not noticed my oil level drop so far.
