One thing I know is that Ecoboosts don't run well without oil. Mine had a filter installed improperly at a lube shop. (double filter gasket, with one pinched). It pushed all the oil out and then I'm not sure how long it ran. We were able to drive it to the dealer, and it sounded fine. It wasn't. The bearings were turned into beautiful, shiny, sliver sand that filled up the oil filter. The engine and turbos were toast.
It is getting a Ford remanufactured engine, as I type this. It will get what I gave it before. Mobil 1 EP 5w30, with oil changes guided by the OLM, which will be around 10k miles. I just have to make sure it keeps the oil in there.
