Just checked the oil today 11-29 and it was down about 1/3 of a quart. Amazingly I can still see through the oil. The truck now has 56525 on the clock.
I had the oil changed at the dealer on 6-1-15 and the truck had 50900 miles on it.
The same thing happened towards the end of the last dump cycle. I had to add about 1/3 of a quart as I was nearing the 5000 mile point. Prior to that, the oil had been dumped in November 2014 with about 43500 miles on it.
I'm seeing a pattern of usage. However, this past winter was a tough one and I was in 4wd for about three weeks straight as SE Virginia doesn't do well at removing snow. I pulled lots of stuck vehicles out and I played pretty hard with it.
Since June, I've been through the mountains at my daughter's college a few times, I've pulled some trailers this summer and the heat this summer was stifling hot right throw Sept.
I've seen similar usage patterns in my 2004 Expy 4.6L.
No, I do however think it's time for an oil change, over time, I think the modifiers in the oil that control viscosity break down and caust the oil to become a little thinner, the additive package also degrades and the oil is not doing as good of a job as when it was put into the engine, a coworker is running a couple of tractor trailers and sees no oil consumption up till about 12000 miles, then he says the engines start consuming oil at a regular rate until he changes the oil, about once every 6 weeks. I don't remember if you change your own oil or have it changed, but I do wonder what is in the oil tanks at the oil change places, typically the oil change places charge less than I can buy the supplies for, just a thought. I think that you keep a pretty good track of your maintenance, so I see no real issues.

Reason: Spell
I wasn't overly concerned but thought I'd get some feedback from the people whom I respect.
The truck has only been serviced by my dealer with a 6-7K mile dump cycle. The service people advised me to change the oil every 5K when I bought the truck in 2011. Ford has been adamant about following the OLM or 10K, which ever comes first. I'm going to drop back to a religious 5K dump cycle from now on.
If changing it every 5,000 miles makes you feel better it's worth a little added expense Tim. I haven't heard a credible explanation on what exactly causes the timing chain issues, so it's possible more frequent oil changes may prevent the issue altogether. I remember GM had a recall to reprogram their OLM in some models to shorter intervals because of timing chain issues.
I'm planning on 5,000 for my first oil change and probably at around 30% of the OLM thereafter.

To me this isn't really about timing chain stretch. It makes sense to me that if at a particular mileage point the oil level is low then a certain amount of oil sheer is happening already. I can't see adding oil just to roll it another 1000-1500 miles which ultimately gets me to my original target dump cycle anyway. I'm good with a 5K change.
Are you a 1/3 quart below the hash marks, or 1/3 quart Bellow the top of the full mark?
If the latter, I wouldn't add, I'd just ride it out.
My expedition uses a quart every 4-5k. I usually don't add till it gets to the very bottom of the hash marks, which works out to a full quart to the top.
Sometimes If I've just got a 1,000 to go until a change ill just add a 1/4 or 1/2 quart so it is well in the hash marks.
