Just bought myself a 01 F350 with 7.3. I have always done my own maintenance on my gas burners, so figured i would do the same with my new powerstroke. I researched on here an other places the process for changing oil and fuel filter (Welcome to guzzle's Ford PSD Maintenance Web Page
Went to store bought 15 qts of motorcraft 15w40 oil, motorcraft oil filter, and motorcraft fuel filter. Now i realize after researching on here the choice of oil/filter manufacturers differ from person to person. I talked to the ford service dept and they recommend nothing but motorcraft, so I figure that is what I should use.
Came home and got started. Drained oil, took off old filter, filled up new filter with oil and installed. replaced oil plug gasket and put plug back in. Added 15 qts of oil (note to self get a bigger funnel). Crank engine let it run a minute or two, turn off and check oil level. Only comes about 1/2 between add and full. I have done some reading on here and seems like some folks say add till you get full even if that means 16 qts. others say it holds 15 qts so put in 15 and leave it. well i just cannot stand the thought of running the truck unless the dipstick reads full so I am gonna be getting another jug of oil and adding till full.
now for the fuel filter. Apparently the previous owner has not changed the filter in a long time, because the nuts holding the plastic "powerstroke" cover were so welded on that I broke them off (both of them). So now I have something else to repair
Then i remove the fuel filter cover, no problem. go to drain the bowl and it won't, realize i should have drained before removing the cover so their would have been some pressure in the bowl to force the fuel out. So now i put the filter back in and cap back on getting fuel everywhere as i push the filter back in. open the drain valve turn the key to start the fuel pump up and it finally blows whatever had the drain tube stopped up out. take cap back off, open new filter and realize that someone has put on an aftermarket filter with the cap permanently fixed to the filter. Put old filter back in. Now, I need to order a new factory fuel filter cap and install the motorcraft filter.
So it was an adventure, but i learned some stuff along the way. So it should be easier next time!
