    yeah they do that with gas too. i've bought far to many vehicles then when i go to pick up the thing is right on empty, hell one time they had it so low i actually didn't even make it to a gas station. now i demand a full tank as part of the deal, if i had diesel i'd be demanding full DEF too

    Our work trucks(F350 Diesel) which we drive cross country multiple times a year, uses about a gallon or so each trip. Unless we are towing of course. Do not let it run empty though. that will mess the engine up quick, fast and in a hurry

    My buddies 13 was going through quite a bit when he first got it
    He had a computer update at the dealer and it started using much less
    Not sure what he's actually getting mileage wise

    The truck will go into limp mode if you run out or are very close to empty, it gives you multiple warning before it gets to that point
    You wont really mess anything up, it just sucks to try to get it to a dealer to get it cleared

    Hello Guys,

    You do not have to fight with the dealer to get a full tank of DEF and gas.!!!

    The dealers are getting paid by RAM as part of the PDI (pre delivery inspection process) to you the customer.

    If they give you any kind of a hard time just remind them of the PDI Process.

    My 14 Jeep grand Cherokee Eco Diesel had 1/4 of DEF when I saw my Jeep for the first time, I reminded them to fill it and I had no problem.

    In my manual it says the 8 gallon DEF tank should last 10K when oil changes are due.

    It should be part of you the purchaser as your process before you sign your name on the dotted line and take delivery to scrutinize every inch of the new vehicle and make the dealer aware of all defects!

    I usually make a list and a drawing like the( rental car companies use to note damage) and get the dealer to sign it an make a copy for myself as part of the dealer form that they use "we owe"


    The Jeeps are throwing different false codes relating to DEF tank and pump their is a TSB here

    http://www.wk2jeeps.com/tsb/tsb_wk2_1801814b.pdf for a PCM Flash.

    I am sure if the jeeps are having issues the RAM's are having the same problem check for a TSB like the one above.

    I bought my truck brand new with a full tank of DEF. I drove about 6900 miles which was almost all highway, and my DEF was just on the bottom side of 1/4 tank. I didn't tow anything during that time. I got a 2 1/2 gallon jug from the dealer for ~$30 and it put me back at almost 3/4 tank.

    Told my dealer to fill it with DEF as well when I bought mine. No issues.

    I have a 2013 2500 and I get about 7000 miles per tank of DEF. FYI, DEF is MUCH cheaper at the pump as opposed to buying it in bottles. It is currently $2.79/gal at my local truck stop. NOTE: You will have to pull into the commercial pumps to get DEF. They don't offer it in the "regular" pumps.
