Here is my latest UOA from my 2015 F150 with the 2.7 Ecoboost. I ran this oil a bit longer than I planned to, about 5900 miles. I took a long trip right before the oil change which put me over the 5000 I was planning on. Looks like a good report, except the Viscosity was a bit lower than the previous run. The oil life monitor was at about 40%, on track for a 10,000 mile interval. It sure seems like that would be way too long for this motor. I recently started using the truck for work, pulling an enclosed trailer at around 5000 lbs. I might go 5000 miles on this oil change, put the Schaeffers back in it.
