Here is the UOA I recently had done on my wife's 2015 Ford Expedition with the 3.5L Ecoboost. Oil is Mobil 1 5w30, filter is a Motorcraft FL-500S: As you can see, the fuel is quite high and the oil is diluted. I ran into this on several UOAs I had done on the 2011 F-150 I previously had, but...

I put a set of clear film covers from Weathertech on my old F-150 and it held up great for 5 years, no yellowing. You can get them from companies like 3M and Lamin-X, too. They're not cheap, though. But for a new car, I think they're worth it.

I run 87 in it, though I've been intending to try 93. I guess I'll get another UOA done at my next change and see if the fuel is still reading high. Since all my metals look OK, I'm not super-concerned. The fact that the viscosity is low bugs me more, especially since this was only a 3800 mile...

As you can see, my fuel is quite high. The truck has been used for a lot of short trips lately, but honestly, that's how it is mostly used these days. When I had my previous UOA done, it was just after a long trip. I wanted to see what it looked like after more typical use. Anyhow, I'd love...

Yes, it's Mobil 1. Thanks for the input, guys, and sorry about posting in the wrong forum, rookie mistake. Thanks to whoever moved it here. I'm not sure about the fuel number, either, though it does seem to be lower than other Ecoboost Blackstone reports I've seen on here. As I said, the truck...

I recently had a Blackstone analysis done on my Ecoboost F-150. Background: The truck has about 11.5k miles on it. First change was done with Motorcraft semi-synthetic at 1k, second was the Mobil 1 you see in this report at 5k. My plan was to stick with 5k OCIs, but we ended up having to take an...
