2018 6.7 knocking??
2018 f350 6.7 started knocking in Saint Louis MO. Drove it apprx 390 miles (expecting to be towed before I made it home) sounds like a rod knocking but i don't believe it would have made it 390 miles without throwing the rod. Its had regular oil changes every 5-6000 miles. He uses Lucas diesel injector cleaner in it from time to time. Had to replace battery the day before and cleans his k&n filter all the time. It has apprx 165k on it & is no where near paid for. I need help!!!!

Yeah that's a boat load of miles, so fuel has probably been from a lot of different places, and your injectors are most likely the source of the knock. Take it to a reputable shop and have it looked at, or a dealer would be fine too
