I convinced the dealer to let me try Delvac 1 LE 5W30
http://www.mobil.com/Lithuania-English/Lubes/PDS/GLXXENCVLMOMobil_Delvac_1_LE_5W-30.aspx
in our X5 35d diesel while still under warranty.
I'm doing a 2nd UOA of Castrol SLX Professional OE 5W30 @ 9000mi; I expect it will be exhausted as far as TAN/TBN.
The Delvac has twice the TBN (12.6) but only 1.0% ash, 800ppm P, I'm hoping to get double the oil lifetime (at least 15K miles) and hoping my breakin sized Fe levels start dropping.
One of you recently posted me that it is now FF on diesel Sprinters; very similar engine and emission system to the BMW.
Let you all know in about 10-11 months.
