I have a 4th Gen, DRD, DRD upgrade, 76,000 on the clock was using Hotshot EDT before the soot cooker fell off, and it may just be me, but it seemed to reduce Regens.

Now that that’s no longer an issue, I wonder if there's any benefit to using an additive?

Does anyone else use one?

Am I just needlessly pouring extra money into the tank?

Thanks for your help!
