If I used lubro moly engine flush prior to an oil change, I'd get 2000 miles before it would use a qt, but would then clog again and I had to repeat the cycle.
Another tip is switch to Shell Rotella T6 5w40 oil. Not only is it impressive in all areas, since it is made for diesels it has more detergents in it and will help clean the oil control rings. E46 fanatics has several guys who did black stone analysis with Rotella and it was good stuff. I use it in my current 330 and it slowed consumption on this engine as well.
Good luck!
