I'm assuming I have a leak somewhere. Oil consumption is roughly 1L/1k miles. I don't see any obvious leaks on pulley/exhaust sides of the valve cover. Haven't had the belly pan off yet this year but that'll happen when I do both tie rods.
Within the last 2-3 years I've had the OFH and pan gaskets replaced and haven't seen anything that looks like a leak or a seap from those areas.
Car is stock with the exception of the K&N air filter. Hardly redline it. I've been using Castrol Edge/Mobile 1/BMW 5w30 for the life of the car. The plugs were changed last summer around 200k and the coils a few months after.
All O2 sensors have well over 100k on them and I know they should be replaced but haven't gotten to it yet.
Thanks for the feedback W37V!
