Racor, aFe, and K&N all make oil filters that will work in your diesel truck. If you want to use the same filter that your truck came with from the factory, opt for a Motorcraft oil filter.
Of course, the best oil filter for a Ford 6.0 diesel truck depends on how you use that truck. Your driving habits determine whether you need something for dirty, heavy-duty conditions or whether you can get away with something less intense. The forums don’t know everything about your life and your vehicle!
Remember to change your oil every 5,000 to get the best performance out of this model.
