Have you changed the fuel filter and stuff like that? Might be the issue.. Could be a list of issues.. Not sure what else to tell you to try... Good luck

scobugpak , I assume that you have verified the accuracy of the odometer...and that the transmission is shifting into high gear...leaky injectors?? Timing?? Low boost?? How does it run? And finally, is this a new problem, or has it always gotten this mileage? Good luck...Diesel will probably get to $3.00+ a gallon in the near future...Where is that cheap oil from Iraq?
