I use 5W30 Mobil Dino and the Motorcraft FL-820S filter
The mods up to and including '01 were 5W-30, those built '02 and newer are the 5W-20 motors... for warranty requirements. Less and less '01s and older are under warranty anymore.
Use what you feel comfortable with, but if your motor is under warranty be very careful your oil meets the manufacturers requirements for viscosity. Ford figures out you've broken the engine do to the wrong oil (and that'll be the first thing they check - R&D loves this) and you can kiss your warranty rights goodbye.

I wasn't sure on the changeover year. I hope that foot didn't tase too bad!!
I have had no problems with the 5w20 Motorcraft oil and filter after 57,000 miles. It uses no oil between changes and the inside is very clean. I tow about 7,000lbs at times in 90+ degree weather with no signs of oil breakdown.
I think that these engines will run forever if properly maintained.
My sister in-law has a 93 Mark VIII with the DOHC 4.6L with about 190,000 miles and it runs like a scaulded dog. I hope my 5.4L runs at least as long. I'll probably have my 01 forever.
