RE: Bad mpg and power 4.7mpg This is odd. Cummins released TSB220085 26-Apr-2022 "Aftertreatment Diesel Particulate Filter (DPF) Maintenance" focousing on ash removal. It discusses Air-Only Cleaning and Liquid Cleaning. It says Liquid Cleaning is the most effective. The TSB does not mention shake and bake. I know for a fact that UPS was experimenting with liquid cleaning as far back as 2017. Their preliminary results were that is was the most effective process for removing ash. I don't understand why UPS and Cummins are involved in such a destructive process. Is this to wear DPF's out sooner and promote the sale of new? | |||
