Thanks. Its good idea to keep an eye on it. When I took my MH to dealer for the Michelin recall there was another guy in for the same thing. The dealer on its own noticed the oil down two+ quarts on his vehicle and initiated a consumption test.
I'm going on 2K mile trip in a few weeks and I made a note to pack some extra oil. In the past it burns about a quart in 3K miles-which to me is pretty normal.
I see on the bulletin you mentioned in your post it is one quart per 3K miles:
https://www.ownersite.com/tsb/tsbs.cfm/2013/FORD/E-450/If the bulletin above is correct, it seems pretty generous on Ford's part to fix an engine which burns a quart in nearly 3K miles. I'm not sure I'd want an engine pulled for such consumption-always room for error in that operation. Maybe if oil was headed into one cylinder and fouling the plug?
Best summary I could find (I do not have any access to paid accounts to check the TSB):
FORD Certain 2011-13 E-Series large vans may use excessive amounts of oil. In T.S.B. 13-6-9 issued on June 13, Ford said that consumption of more than a quart in 3,000 miles had been found on some vehicles with 5.4- or 6.8-liter V-8s. Removing the engine — yes, that’s Ford’s directive — and replacing the valve seals should stop the oil usage.
