Hi, I have seen an article from the BC Diesel portal, Diesel Particulate Filter cleaning for light and medium duty diesel. I think it is new to the motor world. I have seen DPF cleaning for the heavy duty diesel, but most of you are unaware of this current trend, I hope. I have always thought it is better if the DPF cleaning available for the light duty diesel. Because it can remove the soot present and improves the efficiency. How could you do DPF cleaning for the Ford 1500 truck? How much it cost? Had anyone tried?
