Here is my third UOA on my ecoboost and second with the Kendall FS and used a MC FL-500s. I wanted to run this sample past 6K to see how it compared to beercan's UOA that he had with the elevated AL with the Kendall.

My AL did not rise with the longer run like his so not sure what is going on with his.
Blackstone comments: Fuel dilution improved in this sample. It was still present at 1.3%, though this better than the 2.8% we found last time. Hopefully it will stay below 2.0% in future samples. Wear increased, mainly due to the longer oil run. As you can see, iron is the one metal that will track most directly with miles, so it's fine. The other metals should stay low and they did. Insolubles were nice and low at 0.3% and this shows excellent oil filtration. No anti-freeze was found. Silicon held steady, showing excellent air filtration. The TBN read 1.5,good. At 23,379 miles, your truck is doing well!
I can believe the less fuel in this sample but there is definitely some fuel in the oil as i could smell it, the flash point was higher but the viscosities were also lower so I'd assume some shearing with a little bit fuel dilution. I still have some life left in the oil as the TBN did not drop.
I could probably be able to get by with a conventional oil for the miles but I will not use a conventional due to the twin turbos and direct injection. Call me paranoid or wasteful but I want to give my turbos best chance for a long life without coking or problems. My wear rates on a per mile basis did go up a very minuscule amount - not enough to make a difference. I will run the next sample to 6500mi again but that might be quite a while as I will be driving my Taurus to work and the truck will be in the garage. More than likely will hit the time limit before the miles for my warranty. I refilled with more kendall FS and a motorcraft filter.
