B58TU heavy oil consumption!!!! HELP PLEASE!!
My M440i burned 2 quarts of 0-20 within 3k miles on the oil, I did beat on it 90% of the time tho.
What’s concerning is I switched over to 5W-30 and it burned a quarter/almosthalf of a quart within 500 miles on that 5w-30 oil..
I also have a Oil smell in the cabin, no smoke out the exhaust, and no smoke out the oil cap when I take it off. I’m lost.
