Liqui Moly Leichtlauf High Tech Engine Oil 5w40 with 1.5 Cans Liqui Moly Mos2 additive every 7-10K.

150,000 Miles on this N63 in a X5 that is driven hard in the Arizona heat.

I have taken it down to due the valve guide seals and clean the carbon buildup on everything from the notorious leaking valve guide seals the N63 suffers from.

Cam journals and cylinder walls look excellent.

IMHO BMW turbo engines need 5-40 due to the high operating temps, I noticed immediate smoother running when I switched to it.
