Oil consumption - N63 and S63 both the same issues?

[LennyBoy1]

Hi everyone,
I am considering selling my 2008 BMW 3.0si and getting a 2010 to 2013 X5 50i or X5M. I know that some of you might tell me to keep my 2008 3.0 liter and forget about the 4.4 V8...however I’d like to try one out. From my research, there could be or seems to be oil consumption issues with the 4.4 Twin Turbo engines. I did several searches on this site but I didn’t find much regarding oil consumption on the X5, specifically on the 4.4 twin turbo N63 or S63. Does anyone have any experience regarding this issue and what should I look for when picking out my new (used) E70 X5 50i or X5M..? Thanks for your advice.
