If I was like the OP and just started dumping various concoctions into my engine just because I "heard good stuff about" it, I'd have no room left for the actual motor oil in there.
If you was like the OP, you might start dumping various concoctions into your engine, until there was no room left for the actual motor oil.
But the OP's original statement and question was "Just changed my oil to my usual fill of Mobil1 0W-40 in the N54. Was thinking about adding some Lubro-Moly MOS2 to help reduce friction etc. Will it be OK in this turbocharged and direct injected engine?"
So, to answer your concern, adding Liqui-Moly MoS2 Anti friction will not use up all room in the engine, to the exclusion of actual motor oil.
To answer the OP's question, yes, MoS2 might be helpful. BMW recommends a 5w-30 oil, but like a lot of turbo Subaru owners, BMW turbo owners switch to Xw-40 - probably to cut down on oil consumption or maybe some hidden fear of the turbo trashing the oil. The OP might consider using MoS2, which will handle any extra oil demands the turbos might ever make. And as an added benefit, he could probably go back to the recommended 5w-30 weight oil. His engine would run as well or better, oil consumption should be reduced and internal engine friction should be reduced. That's what Liqui Moly says its MoS2 Anti Friction product will do. You don't dispute that, do you?
The OP didn't say if his vehicle was under warranty or not. The BMW bumper-to-bumper warranty is 4-yars or 50000 miles, so he might be right at the end of the warranty. If so, his choice is more difficult simply because of legal issues, not technical issues. But if he's out of warranty, it's time to start learning about the car.
Or, he could get in the line and press +1, +2, +3.
