Making Oil?
#1
#2
I did my first oil change @4700 miles and fuel content of
that oil was <0.5%. Less than 1/2 of 1 percent.
If you search on here, you can probably find the thread
where I posted the oil analysis.
So, no, not making oil at the moment.
Others have had higher fuel content. Some of it depends
on your driving style. Frequent short trips results in more
fuel in oil.

To be clear: Blackstone Labs does not test for fuel content. The run an open-cup flash point test, and 'extrapolate' a fuel content.
DysonAnalysis.com
runs actual fuel measurement, rather than an extrapolation from flash point. Dyson's testing is much more sensitive (and accurate) than what BS gives. They also do closed-cup flash testing. We use Dyson for our fleet.

But their basic analysis is $59, which is nearly 3 times what Blackstone charges!
If I had a commercial fleet that I expected to go many thousands of miles I might invest in that, but for my under warranty truck I'll just stick to the Blackstone reports!

I understand the expense; I sometimes swallow a little hard at the $129 for my personal vehicles, but it's been worth it to correcting things that were going amok early on.
My issue (speaking of personal vehicles now, not specifically the fleet) with Blackstone is that they are an extremely poor value, IMO, for what you get. The $12 - $25 analyses through your local oil distributor give you as good and as accurate info as BS, and I always got TBN from them for that price. Dyson is worth it to me for the better info, but if I wanted to spend less on each UOA, I wouldn't look at BS.
BTW: I couldn't get to our fleet UOAs earlier, or I'd have posted, but our new trucks are showing ~0.5% fuel after 500 - 600 miles. That's with <1,500 miles on the engines, though, so I'm hopeful things will tighten up over the next couple to few thousand.

Also, I'm not familiar with local oil distributors who perform these analyses. What companies to that?

I just bought one of these rigs, and have had a hard time analyzing this issue. The dealer told me that the DPF injection was exhaust stream, but what I've read seems to indicate that regeneration happens in-cylinder, which is what leads to oil dilution. Does anyone know the particulars of this well enough to give me a "final answer"?
Thank you so much.
