    I recently bought a 2013 ram diesel. It had 50383 miles and the price was good.
    The DEF gauge read full when I bought it and about 1000 later still reads full. Is this normal?
    I haven't towed or had any weight in the truck yet. Most of my driving has been around town.

    Please take this with a grain of salt because all I know is what I've read. I think a full tank of DEF will last you 7000 to 10000 miles, the most important thing is never let it run out of DEF because an empty tank will prevent engine from starting. If all else fails take it to Ram dealer and talk to someone thats knowledgable on the Ram diesel.

    Absolutely normal!

    Get a box at 1/2 empty, cheapest I've found, not at a pump is Home Depot. Just $11.

    Mine last almost 8K before it goes half.

    I don't tow, but the more you tow, the more it will be used.

    Thanks, I was starting to wander if there was an issue.

    Mine kinda sat there too but then it started dropping. I don't think the measurement is entirely linear.

    I know this thread is a little old but I wanted to share some info from the Diesel Tech that bought my truck new. He works at a Ram Dealership and advised me to only refill the DEF when it got to 1/4 tank of less. Then, if possible, add the DEF at a truck stop with a pump. For two reasons: 1. DEF crystalizes as it ages so use as much of the older in the tank as you can before adding more. 2. Purchasing DEF at a truck stop should be fresh and you buy what you need. Less mess and no need to store extra. Don't stock up on DEF and check the dates on any container you buy.
