The question was, is the oil you're using approved for your engine? You haven't answered that and ard doesn't want us to have to look it up.

Its wacky because you believe you are experiencing excessive oil wear, i.e., your oil is wearing. Oil "wears" in use, sure. Have you analyzed your oil, though? Besides, ALL oil "wears" some. What makes you think your "wear" is excessive?

It's simple. Add oil to maintain proper crankcase oil level. BMW didn't provide a dipstick on your vehicle so that requires a PROPERLY operating electric level sensor. Sounds like it might not be working correctly.

Maybe fix that first.

Maybe drain and refill the oil several times at fixed driving intervals to obtain your oil consumption and add oil at that rate between proper oil and filter changes.

Maybe draw an oil sample and have it analyzed.

Or don't fix the sensor or look into it any further. Don't try to obtain an accurate oil consumption rate. Don't get your used oil analyzed for wear metals.

Adding oil to maintain proper level will not affect the oil analysis results adversely. A reminder, one analysis in isolation is worthless unless it shows gross contaminants or wear metals in which case, further attention in the short term might be warranted.
