At 63,000 miles, my 2.7 has had a steady diet of Motorcraft 5w30 semi syn every 7000/7500 miles. I got the mileage OCI from analysis and the oil brand from the owners manual and backed that up with an example of the highest mileage 2.7 I'm aware of. Pat's 2016 2.7 uses the Motorcraft semi syn and gets changed when the truck tells him to....which works out to every 10k. Pat's truck recently turned 400,000 miles.
