I cleaned my 2017 Ecodiesel Ram with the Liqui Moly particulate cleaner. I flushed it afterwards with a Liqui Moly flush solvent. It restored the particulate filter. I drove the truck and it smoked for about 12 miles and then it cleared the particulate filter and it ran like new. I cleaned mine on the vehicle using a pumped up bug sprayer can. I just removed the DPFluid injector and stuck the cut-off end of the sprayer through that hole.
