I filled up the DEF tank and have run a full tank of fuel through the truck, the DEF gauge hasn't moved. I even drove 8 miles down some dirt roads, I figured the rough road would have knocked the level sensor loose if it was stuck, anyone else have this issue?

is it below -11 C (12 F) where you are? DEF tanks are known to freeze and then the guage won't move till it thaws out. If it's not frozen, not sure.

I can not notice movement on my DEF gauge in a single fuel tank. I'm getting 1100 MPG on the DEF so it goes down real slow.

That's kind of what I was wondering, as the sales guy told me a full tank of DEF only lasted about three tank's of fuel. But I would have expected it to move since I've driven all most 400 miles since I topped off the DEF.

Yes the DEF should typically last a LONG time under normal conditions. I've used only about a 1/4 tank of DEF according to the gauge over the last 2,400kms (when I bought the truck). Don't worry - I'm sure it is just fine.

I just got a 2016 ECO Diesel last week. The DEF gauge was about half full when I got the truck which had 550 Km's on it as a demonstrator. Either the DEF tank was never filled completely, or it used a lot. I think they probably put just enough in the tank to half fill it to keep their costs down, and although they topped up the fuel tank, they never did that with the DEF. I have put on about 350 Km's since, and the gauge has not moved. I am going to buy some to fill the tank, but am wondering if I can look around to get the cheapest product and if there are any concerns with using a cheap fluid as opposed to whatever it is the dealer recommends.

Disregard this as I found the info on another post, along with the specifications etc.
