Pre-2014 N63 (not N63TU) engine lifespan?

Hello. How long can these engines last? At what millage they need changing tensioner, chain, injectors and so on. Please write from your experience. What was faulty on your 50i and at what millage. Thank you.

P.S.
Please write when was your car produced and it has black engine cover or grey.

Many people say that it burns oil after 40k. Chain , tensioner and some parts must be changed after 50k. Is not it right?

My 2012 X6 50i (Black Engine Cover) starting to burn oil after 50k miles. I am sure the engine will last a long time if you keep doing your regular maintenance and replace parts. So far the most expensive things I have replaced for this car are upper/oil pan gasket, Vacuum pump, Injectors (Under Customer Care Package), Front Driveshaft (Under Customer Care Package), Transmission fluid mix and programming.

Currently I am at 65k miles and I am planning to keep the car until 100k miles for sure. It is a great car for sure but expensive to keep. Something I have to watch out for will be O2 sensors, valve stem seals, torque converter (vibration on the low end accelerations)



btw my car was produced in 07/2011

I am at 105k, and it burns oil like its $3 a quart. Knock on wood other then that nothing too hateful. I have done a rear o2 sensor, and I currently have one bad coil pack.

I am doing 10k oil changes because I am doing a quart of oil every 500-1000 miles. If I the low end of that is because one time I was using Castrol 5w-20 when I saw the 500 mile oil usage. I have transitioned to 15w-50 Mobile 1. It is cheaper when I can buy the 5 gallon jugs for $26, vs the $10 per quart on the Castrol synthetic oil. It has also held in the motor a little better, so the oil usage may be a combination of PCV usage, and valve seal usage.

Do not use 15w50. Use only 0w40. 5w30 or 5w40. 15w40 is not approved for bmws.

The M's run 10/60, so we will see what happens with 15w50. I have had it in the truck for a good bit of time now.
