Bit of viscosity reserve and a turbo-worthy oil too. Your 7.xx viscosity isn't great. That's a...

    2015 Expedition Ecoboost - M1 5w30, 5123 miles

    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: <img src="http://i1024.photobucket.com/albums/y310/tspangle88/15%20EXPEDITION-161228_redacted_zpsq0kmrvic.png" class="post-image" alt="" />...

    Maintaining clear headlights

    I put a set of clear film covers from <a href="http://www.weathertech.com/lampgard/" target="_blank">Weathertech</a> 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...

    M1 5w30 - 3815 OCI , 29113mi, 2011 F-150 Ecoboost

    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...

    UOA on 2011 F-150 Ecoboost

    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...

    UOA on 2011 F-150 Ecoboost

    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...
