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

I usually top up my DEF at around 6000 miles or when it shows 1/2 full. Use of DEF is proportional to fuel use, thus when towing you will use more fuel and more DEF but even so you are not using much DEF
