I have a first-gen Ford EcoBoost 3.5L V6 in a 2015 Expedition, the owner's manual states to follow the oil life monitor, but I run an OCI of 5,000 miles, as there are known issues with extending OCI's that have manifested with the timing chain - the chain becomes worn and stretched. As the chain is stretched the PCM detects the changes in camshaft position and sets code P0016 for crankshaft/camshaft correlation. Ford's issued TSB 14-0194 about this.
Ecoboosts, also seem to have a reputation for higher than normal fuel dilution. I believe it's a byproduct of direct injection, added to the fact that the EcoBoost's turbos are cooled by both oil and water, so the oil is going to be exposed to quite a bit of heat. Plus I tow fairly often.
The Ford spec oil, in my manual, for this application is a 5W-30 that meets WSS-M2C929-A which I think may be API SL/SM which can be met with the Motocraft synthetic blend. In the new second-gen Ford EcoBoost 3.5L V6 the spec changed to WSS-M2C946-A, I think this was an alignment to the API SN oil hitting the market.
I have been using Pennzoil Ultra Platinum 5w-30 since my first oil change which meets the Ford's WSS-M2C946-A spec. Here is my question - two weeks ago I drove back home from FL to NJ and went to do my 30k oil change, and I didn't have any of the PUP 5w-30 left, but I did have a case of Pennzoil Platinum Euro 0w-40 for my Fiat Abarth - so I just used that instead. Everything being subjective, it seems like the SUV runs a little bit smoother on the Euro oil, and it feels a tad more responsive - this could also be a Pavlov's Dogs effect . The Euro oil obviously meets or exceeds API SN but doesn't reference any US auto makers spec's - plus it's a different weight than spec'd, what are some opinions about make this the go forward oil that I use in my Expedition?
