Most deisel stations off of major highways have high flow filters at the pump for quick big rig filling, while convenient it can also send contaminants into the fuel. Corrosion from the tank, dirt etc. Deisels seem to always benefit from additives and each additive seems to have a dedicated following including lucas

If possible try to use smaller non big rig stations. Most of my knowledge on deisel is torque over horse power, and some diesel guys will like to brag about getting 19 mpg highway using a programmer and removing emissions systems.
