Oil sample and Molybdenum

[bluebimmer]

I just received the oil sample that I sent in through work and was wondering if these figures sound in range:
Si = 2
Mo = 175
Fe = 10
Cu = 1
Sn = 18
Al = 2

I guess these numbers are ppm? I'm new to oil sampling and am not sure. I use Penzoil 10W-30 in my car (98' 328i). Why is the Mo so high and what internal parts have Mo in them? Thanks

Some oils use molybdenum as an additive to reduce friction. Mobil 1 is high in molybdenum.
