How much DEF does your diesel use?
I have a 2016 F350 SRW 4x4 and tow a 34' fiver. I topped off the DEF tank before leaving on a short trip last week. Trip was about 300 miles round trip. So, today I decided to top off the def tank again. It wouldnt hold a teacup full, which surprised me. My previous 2011 6.7 would have used a half gallon to a gallon on a 300 mile towing trip. Anyone have a clue or do the newer trucks use a lot less def? It just rolled over 10K miles this week.
