I don't see a problem. You ran the oil longer so the wear increased more.
You run Mobil 1 EP for 5000 miles?????? Why not just Mobil 1 for that distance?
I can't see the picture.
I don't see anything wrong with that. Looks good to me. Looks like the 4.7 is a touch hard on oil.

I don't think I'd call 3.3 prematurely degraded. If you look at the current literature on what has changed with motor oil recently: the manufacturers are using additive packages that start with a lower TBN but maintain the TBN for longer.

Yeah 3.3tbn isn't bad. gasoline oils have a lower tbn. I think they start at 6 or 7.
Has the gas mileage chip helped your gas mileage?
This is not a bad UOA, and the TBN would last you until 10k easy. If you don't like it try something else, but these #s look pretty good to me.

We'll over the last tank it has increased by ~1.4 MPG,But that isn't enough data to really bear any statistical conclusions so I can't say for sure.
