My X with 175,000 miles on the V-10, uses a quart to Florida, and almost another quart on the way home, and I use 5-W-20. And I think even that usage is caused by a dirty PVC valve.
I hate to get into an oil debate, but do you think a 0-W-30 or 0-W-40 synthetic European formula would work better? I use it in my BMW with 125,000 miles and it never uses any oil in its 10,000 mile change interval.
FWIW, I own an F-250 w/165K mi. and a BMW 530. The truck uses about a quart between oil changes and the BMW uses about a half quart. I use Motorcraft 5W-20 in the Ford, exclusively. The BMW gets whatever full synthetic is on sale.
You could try using a thicker (say 5W-30) full synthetic in the Excursion but a couple of quarts usage while towing wouldn't be out of line, IMO. What speeds do you tow at?
