Still annoyed with how much def this thing uses, I was getting 2 mpg better than my 2018 before this 2022 started all its smog regen crap. Now its worse, If I were in a free state I would smog delete it. I know its a federal thing but there is no way the wasted fuel and def creates a net cleaner environment.
I am in CA, all the truck stops sell biodiesel so that means I have to drive the trailer up front for regular diesel and out back for the Def. Wasn't as bad when I got 5-7k miles per tank of Def, but now it looks like I am every 2k miles

And, DEF usage has nothing to do with regen cycles.
And, DEF usage on mine has been very high lately too, sucks that 7.5 gallon tank up faster than my old RAM would go through a 5.5 gallon tank.

Just made a weekend run to Ohio in my buddys '18 Ram. 3500 miles total, it took 7 jugs of def to make the trip. we were pulling a 26 ft enclosed car hauler type trailer getting ~9 mpg. Absurd how much of that crap these diesels take.
