MY: 2017
Miles: 20k
Oil: 0W-40 BMW LL
Fuel: Pump RON 95 for daily, 98 or 100 for track days (European gas)
Tune: Stock
Burn: Nothing measurable
Last oil change: March 2019
Miles since: ~10,000
Track days on Current Oil: 6 (One more coming up in September)
Next oil change according to iDrive: March '21 or another 6K miles. Not a day before.
Do you guys think I'm pushing factory oil too much? Not asking to argue, my mind is made up. Just curious what others think.

Several shops have done tests including HP Autosport I (believe) showing how horrible the factory oil is on the M2 (in regards to tracking). And they recommended changing after 1-2 track days max. It was bad.
