Hi all,
I recently did the first oil change on a new-to-me 2016 expedition with 3.5 ecoboost with 120k mi.
The Ford dealer I bought it from had changed the oil just prior to my purchasing it and the appearance of the oil changed gradually through the 5K OCI from clear to brown toward the end of OCI just as I would expect with no discernable oil consumption.
I don't know what kind of oil the original owner used or interval.
After filling with Penz Plat 5w-30, the oil went from clear&bright to dark brown and opaque very quickly, less than 1000mi. So I'm assuming there's some sludge or varnish that's being dissolved by the PP.
If that's the case, is a bunch of dissolved sludge a problem? And would it be advisable to go ahead and change the oil again soon?
Thanks,
Walter
