The more a person drives in boost the more blowby a motor gets. It happends no matter what kind of motor tou have with forced induction. my mustang has a $10k motor built with tight tolerances and stainless total seal rings and it still happends. I ended up installing a PVC catch can vented to atmosphere on my mustang cause of the gas fumes that accumulate. I'm going to do the same in my Eco. There really isn't much that can be done about it. When the motor goes into positive manifold pres the motor rich'ens considerably otherwise running lean will destroy the motor.

i use blackstone as well, and they told me they'd keep an eye on the amount of raw fuel in the oil.

It is surprising just how much research and effort manufacturers put into lubrication specifications. They usually plan for all of this. My Ecoboost Lincoln didn't have this problem, but my drive cycles were fairly long as it didn't experience any short trips.

What about the 2.0 litre Ecoboost folks? Have those with that engine had a chance to break in enough miles to start commenting?

I'm thinking one of these just may go BANG!

Check with your local Cat dealer for oil samples. They are generally around $15 and have just a couple day turnaround.

Cat Dealer? Explain!

Caterpillar does oil testing, just like Blackstone labs and a few others. You can get the collection material from a local dealer and send it too them for testing. Though I've only ever done it for diesels. But oil is oil.

Ok, I thought that was what you meant! But I wasn't positive.

Remember Ecoboost engine 448A , the "Hero" engine? When Ford tore that engine down at the NA auto show I was amazed at how clean the innards were. Supposedly it used Motorcraft semisyn 5w-30 taken to the OLM's recommendation for oil service.

What never occurred to me until this thread got started was that the engine had zero vanish probably due in part to fuel wash. Gasoline will rinse varnish away so it kinda makes sense.

Using gas as a detergent for a high soot engine; Ford just might be sly as a fox....

I have often wondered about that engine. While I do not dispute the results of that tear down, it kind of makes me wonder how an engine that saw so much abuse and use was able to maintain such little wear and tear. I guess it waits to be seen as there aren't enough people in the real world who have had a chance to rack up that kind of mileage yet.
