Happened to go by a pilot -fly J on the way home the other day and decided to use their def pumps since we will be taking two long rv trips soon...

have only 5000 or so miles that included 2 towing trips of about 2000 miles total and it took a LOT of def !!!


NOT - only 2.2 gallons
which is less usage than I expected (and IIRC, I used more on the 2011 ?!?)

 

Who knows. I wouldn't be surprised if Ford refined that system a little since the early builds.
I'm at 4,000 miles on this oil change/def fill and it's been under half for awile now so I expect the 800 MTE to show up soon.
