Basic maintenance for your diesel engine is relatively easy. For the early diesel engines ie: 6.2L, 6.9L, 7.3L indirect injected non turbo engines as well as the later model turbocharged & direct injected engines here are some tips. One of the most important items to maintain regularly is the replacement of the fuel filter (s). Changing the fuel filter every 5,ooo miles on systems that have only 1 filter is recommended. If your vehicle has 2 fuel filters, a primary & secondary filter you can go to 7,000 miles before replacing the filters.
It is also recommended that a fuel additive be used in the fuel system to help keep it clean & lubricated. On late model vehicles that have only one fuel filter, adding a primary fuel filter is like taking out an insurance poicy on your fuel system. The better the filtration, the longer the fuel system will operate without premature failure.
The next item which is really the easiest & one of the most important to maintain is changing the engine oil & filter. Engines with & without turbochargers on them must have regular oil & filter changes done. You need to change the engine oil & oil filter every 3,000-4,000 miles to help keep the engine clean & lubricated properly. Changing the engine oil & filter on the late model diesels especially the Ford Powerstroke is extremely critical since the injectors are lubricated & actuated by the oil system. It is recommended that you use Delo 400 with a grade of 15w-40 or equivalent in the newer engines. Make sure you dispose of the used oil & filter properly. Also, do not forget to replace the air filter.
The 3rd item that you need to maintain is the coolant. A 50/50 mixture of clean drinkable water & coolant will usually give freezing protection down to -34 degrees F & it will also give boiling protection to 265 degrees F. On the early diesel engines especially the 6.9L & 7.3L Intenational engines in the Ford pickups there is an additive that should be used in the coolant system to prevent electrolysis from happening.
That is basically all that is required to maintain your diesel engine.

what would make a 6.2 litre diesel engine stall like it ran out of fuel when the engine warms up to normal running temperatures?when it does this,you can start it back up and drive again for a few miles and shuts down again... it don't have a problem driving when it is cold in the engine, just when it warms up
