What maintenance should you do to a 7.3 diesel engine?

Well you should have a maintenance guide for your truck listing what should be done and when. If not look for one online to use as a general guide.

Change the oil at the recommended intervals. Make sure to always use on-road diesel fuel. Off-road diesel fuel is much dirtier and typically illegal for on-road vehicles in most states. Make sure your fuel filter is replaced when recommended and the air filter is clean.
