Had the privilege of wondering the back end of the local Ford dealer today while doing some work there. So of course took the chance to check out the bulk oil. Turns out its Mobil 1000 in 5w20 and 5w30 and 10w30 delvac for the diesel folks. I would assume all the ecoboosts are getting the 5w30 for the basic LOF change. Lots of 1L botttles of Motorcraft 5w20 syn laying around too.
