2006 X5 3.0i M54 engine 6sp MT with 122K miles.

1. Did the LOWER end treatment:
- 3/4 qt ATF for 200 miles.
- Ten (10) minutes before oil change, one bottle of Lubro Moly (500 mL) into engine oil. Ran engine at idle for 10 minutes.
- Changed engine oil and oil filter.

---> No change in oil consumption: still 1qt/400-500 miles!


2. Did the CCV Mod (Duralast 1124 Valve as in the photos).
- After 500 miles, zero oil consumption, unbelievable.
So this CCV Mod rocks!!!

Thank you all for saving my motor!!!
