I had an 08 diesel that didn't use DEF, it would inject fuel into the DPF, when that regen would happen your MPG turned into how many gallons per mile!
Your still pumping fuel for a regen. DEF is injected into the SCR which is after the DPF.
The addition of DEF fluid allows less regen and a better regen while controlling NOX out tje tail pipe. Which equals better fuel economy with less regen.
