    DEF UsGE

    Hi Everyone,
    I have a general question on DEF usage. I have now driven my Cab and Chassis 2018 Ram 3500 DRW 4x4 just under 3k miles and used about half the DEF according to the gauge. Is that typical? I do mostly highway driving and tow a horse trailer with living quarters about once a week.

    Thanks in advance for any help.

    That sounds about right especially pulling a trailer once a week.

    if its the 3 or 4 gallon tank that sounds right, if its the 8 gallon like the 5500 C&C, that may be a bit much depending on trailer size and weight. I do not drive the 5500 at work, so I am not sure of its DEF usage.

    Thanks for the answers. I believe the DEF tank is a 9 gallon tank so it sounds like it might be a bit much. How do you adjust the amount of DEF used? Is it something that I have to bring to the dealer?

    Check your tank size before jumping to more conclusions. as for adjusting DEF usage..... As far as I know, there is: Delete: usage = 0 Stock: Usage = some (my 2016 2500 got around 1000 MPG of DEF) EGR-less: Usage = more than stock (I haven't paid enough attention to DEF usages to give you an MPG of DEF)
