Its still running but thats about all i can say for it. I filter the oil in several stages ending with a1 micron filter and havent had anything plugged. but the injection system was in bad shape when i bought the truck and its worse now but i cant say if it was used oil that is finishing it off or it it was inevitable. The truck doesnt owe me a thing i could still part it out for more then i have in it and it gets me around for free when i want to fight with it. i have 4 or 5 more pumps for it i may put one in it and see what happens
