Mobil 1 0W-40, 1150 miles @ 6400 miles total, in BMW 335i, Twin Turbo DI 3.0L I6. Another example of a fuel diluting monster.

RS4, thanks for posting this. Do you know what the off the charts boron means?

Why is B called a contaminant? It's almost always an additive. I'm sure at 165 ppm it's an add.

Nice flashpoint!

Pablo, a quick google search says that Boron Nitride and Boron Nickel are used in gas turbines. I'd guess that in wear analysis of a turbine that boron might be considered a wear contaminant.

Wow - exotic turbos in a BMW. Cool.....but wow that much B wear is troubling. Are we sure there is no B in M1 0W-40? Most M1's (and many other oils) now contain Boron from 50-250 PPM.

VeeDubb, Mobil 1 0W-40 has 188 ppm of Boron in a VOA on BITOG. I believe it is an antiwear additive.

There is a weird echo in here! I said it's an additive, you said it's in the turbo (or were you refering boron nitriding - hardening in turbine engines?) Oh well same answer

I realize this is not your UOA, but the other oils would be interesting to know as well.
I assume that all the samples were taken when the oil was changed.
What filters were used?
It's funny that 2.26% fuel is only a watch & not a warning.
Any additives?
