Ram 2500 DEF fluid

[samhain7]

Hi all
I am on tank of gas # 6 on my new to me truck and thrnDEF fluid gage has barely even moved

How long do you get on a tank of DEF fluid and how big is the reservoir?

Thanks

It varies. You will use more when towing than when not towing. It also makes a difference in how big the DEF tank is. My understanding is to expect around 1000 miles for each gallon of DEF when not towing.
