Question High Def Consumption?

Anyone have this experience? Any thoughts as to why?

My experience this past week has been about ~900 miles of driving and burning through a 1/4 of a tank on the gauge which in my mind should be about 2-2.5 Gallons. As I always fill it up with 1/4 tank left and the 2.5 gallon container always takes me back up to 1/2 a tank.

I put 2.5 gallons in the tank last week before driving the ~900 miles of about 97% highway travel. Historically I have seen the 1/4 Def tank last me in the 3,000-3,500 mile range. I could literally watch the gauge go down over the course of my travels. It had never done this before. Little concerned.

Anyone have any thoughts or things to check? I didn't see any puddles under the vehicle and there has not been any high temps to cause evaporation.

That definitely sounds wrong. Your 3000-3500/2.5 gallons of def sounds spot on from my experience. I would take it in and have the whole system looked at. Either you're leaking it on the ground, or your DEF injector has gone nuts and has been pouring it down the tail pipe.

My vehicle has not been updated in at least 6 months. Purchased it in July/August time frame. Might not have even been updated when purchased. Originally got to the dealer in Feb of last year.

I have purposefully held off on taking it to the dealer until you guys on here felt happy with the latest updates.

Said otherwise, nothing has changed on my vehicle between seeing 2.5 gallons for 3k-3.5k miles to my 900 mile experience.
