I Couldn't agree more! I use that exact same oil & 2 cans of Mos2 oil treatment every 5k in my n63, which shares every same internal part (save for exhaust camshaft & pistons) as the s63. I am at 182k miles with the original engine and I am now officially as fast as brand new 2022 X5M with the new intake I am making for the 50i & M.
Think about that, 10 years, 182K miles and able to pull the same 3.6 zero to 60 times as a brand new engine in the 2022 X5m(video below). The Mos2 IMHO is what allowed the engine to live this long, I mean this is the engine BMW lost a class action law suit to and very, very few ever see much past 120k miles, let alone one what is tuned to 620+hp like mine.
If you read up on the science behind molybdenum disulfide it makes sense, adding a protection barrier against wear and damage to bearing surfaces. Again highly recommend this combo of LM 5-40 & LM Mos2 Tom mentioned above for the n63/s63 engine family.
