No curve ball.
Not unusual for any engine to burn some oil.
The manufacturers will tell you that 1 quart between changes is possible and not unusual.
Reality is that most do not burn nearly that much.
Even so, to burn a quart between oil changes is no big deal.
Even if you pay full price for synthetic oil - only about $7.
I'm going to leave it at that: I don't think it is out of the range of normal and neither does Ford, but you think it it "unusual" and "no big deal."
I would like to apologize to anyone that has been following this thread. I have had to take a break from my car for a while, so I haven't checked the compression. I would tend to have the same beliefs as Bubabud, I feel that it has a problem. There has to be a physical reason, and I'm optimistic that will be revealed by a compression test.
I changed my oil today, and decided to look into the oil fill hole via an endoscope. The results were unexpected. I have attached images. There appears to be some sort of black deposit inside the valve cover, and I can pull some out with my finger (as pictured). I suspect this is the result of extended OCIs. I can thank the previous owner for that.
I can't understand how people aren't willing to dedicate any more than the bare minimum to their cars. "I'm not going to let the dealership scam me! I'm not stupid! I'm going to get my oil changed every 15,000 miles!" Anyway, here are the images. I wonder if this deposit formation is somehow related to the oil consumption.

Hey folks, I'm sorry it has taken me so long to give some closure on this issue. A compression test revealed normal levels. The way I understand it, a compression test doesn't indicate much about the condition of the oil control rings, so I assumed mine were worn. I was reading about an oil additive called Kreen, which is made here in Nashville. The theory is that a lot of oil consumption issues are caused by carbon buildup on piston rings, which Kreen is designed to remove. After my third Kreen treatment, the oil consumption issue seems to be resolved. It would stand to my layman's reasoning that carbon buildup on piston rings was causing the oil consumption.
I'm not affiliated with Kreen in any way, but I am impressed with what it seemingly has done for my engine. I probably wouldn't have considered it if it weren't made about 30 minutes away.
Thanks very much to you all for the helpful insight while I was dealing with the issue. All the best.
