On my 2012 X5, I did 1200 break in like my M car and did 1/2 cycle oil changes around 7k miles on the V8 turbo. BMW did 1 or 2 other changes due to the warranty/recall work on the V8. It was burning 1 qt every 500-750 miles so BMW did warranty valve guide seals.
The Tech who pulled the valve covers off had to double check the year and mileage and make sure this was the car he had to do guide seals on because he never saw a x5 motor look so clean. Zero sludge in the top end of the motor. He said he had done about 15 guide seals when he did mine. That says something about proper length of time on oil changes. My SA actually took pictures and sent them to me.
