We have a Pierce fire truck with a Cummins engine that we need to have the DPF cleaned. Anyone have a company they can recommend?

After attending Lake Counties mechanic workshop this past summer we had a demo from a vendor they had there and ended up buying the product called Diesel Force. It sends a chemical through the emissions system and cleans everything from EGR valve to turbo vanes to the DPF. We have used it on a few trucks that have had DPF issues and they have run considerably better. Our plan is to use it as part of our PM program. This may be a route you want to look into. It is sold by the Lyden Oil Company out of Portage Indiana, the local rep is in Algonquin.
