One more thing Ford's current Diesel motors are notoriously bad for not liking is biodiesel. Most truckstops are selling a blended diesel with biodiesel added into it. For the big rigs, it isn't a problem because they rarely stay parked for long and burn so much fuel that. A diesel pickup on the otherhand may sometimes sit a few days without being ran, and sometimes a tank of fuel may last a week or two or more. The problem is the injectors. When this diesel sits, especially in colder weather, the biodiesel will jellyfy, so to speak. When the motor is started this jellied fuel then clogs the injectors and whammo, no power. It's actually a problem with a lot of diesel pick up trucks, but Ford seems to be having the most issues with it.
