Soot collector particulate filter


2008 Ford F-250 Super Duty King Ranch exhaust particulate filter

The particulate filter is part of the "Ford Clean Diesel Technology" exhaust system and is responsible for removing soot from burned diesel fuel. This system can only tolerate Ultra Low Sulfur Diesel fuel, but Ford allows a 5 percent blend of biodiesel.

Ultra Low Sulfur Diesel (ULSD) fuel is required for this engine. A 5-percent blend of biodiesel is allowed and it actually enhances the lubricity of the fuel for better fuel system lubrication.
