Byebye. My N63 has been great. Bought it new in 2012 so I had the customer service updates but I never experienced any problems. I have seen a number of N63s opened up and every one of them had a bunch of sludge build up due to oil failure. Made for lots of replacement long blocks and valve seals. BMW did oil changes at 15,000 miles. This was way too long for an engine with top mount turbos. They might have gotten away with it if they were using Amsoil or royal purple. They were using Castrol. I have always done my oil changes at 5000, so no problems.

In 2014 they lowered oil change intervals down to 10000 miles and changed to a synthetic from Chevron labeled as BMW OIL.
