Thought I'd post my latest UOA.
FTR, this is over a 2.5 year period- the initial fill was over Thanksgiving Weekend of 2011, and didn't get changed until about 2 weeks ago.
I used a Motorcraft FL-400S filter, and added a half-quart of Supertech 10w-30 SM rated synthetic at one point, and another half-quart of Exxon Superflo SM rated 30HD at another (both were what I had for my lawnmower).
Conditions: Roughly 18-19 miles per weekday to and from work, with longer weekend trips. Temps ranged from about 108F on the high side, to somewhere in the 15-20F range on the low end. (Dallas, TX)

Code:
It's been about six years since your truck's last sample, and we're happy to report that it
is still wearing well. The only odd find in this latest sample was silicon. We're hesitant
to call this a problem, as wear is okay, but it may show the need for a new air filter. Wear
is reading higher than before but you're also running your oil longer, and that's partly why.
But with a new air filter, you might be able to get better wear numbers than this.
Metals are still average though. No fuel or coolant found. You still had some active
additive left with a TBN of 1.2. Try 12,000 miles.
