7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Mein Auto: 2006 BMW 750Li
06' 750Li Oil Consumption

Good Day;

Would any care to comment on what the average oil consuption I could expect from an average 4.8L V8 2006 750Li engine. I think I am consumeing engine oil at a higher rate, yet I cannot observe any off the clssic "tell, tell" sign of an engine leaking and/or burning oil. Any input will be appreciated, ThANKS.

I have the same car. It has about 116,000 miles now and find that I need to add at least a quart between changes (10,000 miles).
I also have the rough idle issue, and from the reading I have done here, I think it is all related to a VANOS issue.
I am working with the mechanic right now to repair the seals on my VANOS solenoids and will let you know if that reduces my oil consumption.
I also find no leaks anywhere, nor does it blow oil smoke out of the pipes.
