I'd like to see that also. However, it appears that spec isn't too stringent as many "conventional" oils meet it, like Shell Formula 5W-30. Which is fine if you have a port injected non turbo engine. With our 2.3 EB I'm even leery about using the MotorCraft 5W-30 synblend for the length of the OLM. I'll keep that at 5,000 mi OCI's and for longer OCI's I'll use a synthetic such as Mobil 1 since I can get 4, 5 quart jugs a year for under $13/ea

I think I am going to go with 5k changes at the dealer(to have on record for warranty) and halfway through, at 2.5k, just dump the oil(no filter change) and put a 5 quart jug of the Motorcraft in. I really don't like the fuel smell on both our trucks, with our normal driving. Interestingly, there was none of this smell on the recent 2800 mile road trip.
What Ford EB engines do you have? With our "normal" driving patterns and the recent long highway trips I've never smelled fuel in the oil. I changed the "free" dealer fill at 5,200 miles with 3,200 miles on it, no fuel smell. I changed it with Mobil 1 5W-30 which I'm going to change on Tuesday. This accumulated over 7,000 miles in maybe 2 months. I'm going to send this out for an UOA to see how it fared.

They are both 2.7's. Both purchased new this year. I sent out the 2016 oil for a UOA right before the trip.
The 2016 smoked once decently after sitting a couple of hours. This was at around 1500 miles. The 2017 smoked decently once, right as I pulled it out of the garage after sitting for a week while we were on our trip. This is with about 3200 miles. The 2016 smoke was what got me to start looking at this. And it was not fuel or water vapor. It's oil smoke. That is one of the "symptoms" on the TSB.
