Just got back my Blackstone UOA on my 2004 PSD. Everything looks great but the levels of Boron and Magnesium are much higher since I switched from Rotella 5W-40 to Mobil 1 5W-40. Are these 2 elements part of the additive package or is something going on in the engine. See UOA here: http://rides.webshots.com/photo/2409003790070055861cVCRvn
