Let me tell u something about today's diesel fuels, they are getting strait out dry.... All of these fuels where getting at the pumps don't have half the lubricants they used to when these old 6.9s of our where in production. there are additives and everything else but... i know and old diesel mechanic that taught me to put ATF (auto trans fluid) in the tank. Apparently there are so many minerals and rich lubricants in ATF it makes up for this dry fuel Our trucks where never designed to run on this dry of fuel,I think thats part of the reason why alot of the 6.9s injector pups are failing yea they arent exactly the perfect design they are the first diesel engine Ford put into these pickups, I know a few other guys that are having this problem. im having the same problem myself it started this summer and its going to cost me about a grand if i dont do myself. I have an 87 F250 ATS turbo, K&N filter in the box and Im not afraid to say a 4 inch strait pipe, so i have a few extra horses invested in it with about 187,000 miles on it. I usually put about a 1/4 to 1/2 a bottle of ATF in my tank hell the truck will take anything u give it u can put a hole bottle in it if u want it will be all the better. There are other alternatives to keep those 6.9s healthy biofuels are excellent for your motor. I did read an article in Diesel power magzine about this guy that had a early thousend excursion with the 7.3 powerstroke. He was running used ATF and 15% diesel in his rig and it was working fine he said there was a small increase in horse power and fuel mileage. They didnt know how good it would be for the motor but the guys been doing it for awhile and never had any problems. They also said the old IDI motors like are's would also be more tolerent then these new common rail motors would be if there was going to be any problems. So you probaly just got some fuel that was a little watered down or something and ur engine dint really agree with it. Any ways I hope I answered ur question on the subject, good luck and keep that diesel runnin!
